Lilith originally had five dozen water bottles that she needed to sell at $2 each to get exactly enough money to buy her friend a birthday gift. However, at the store, Lilith realized she could not sell at $2 because the regular price was $1.85 per water bottle in her town, and she had to reduce her price to $1.85 as well to sell her water bottles. Calculate the total amount of money Lilith will have to find to buy her friend the birthday gift after selling her water bottles at the reduced cost.

How many water bottles did Lilith have? ** Lilith had 5 dozen water bottles, and since a dozen has 12 water bottles, the total number of water bottles she had was 12 bottles/dozen * 5 dozen =

<<12*5=60>>60 bottles How much money did Lilith need to sell her water bottles? ** To buy her friend the birthday gift, Lilith originally had to sell her water bottles for a total of 60 bottles * $2/bottle = $<<60*2=120>>120 How much money did Lilith have after selling her water bottles at the reduced price? ** When she reduced the price to $1.85 to meet the regular price, the total amount of money she had from the sales was $1.85/bottle * 60 bottles = $111 How much more money does Lilith need to buy her friend the birthday gift? ** To buy her friend the birthday gift, Lilith has to find $120 - $111 = $<<120-111=9>>9 more #### 9 John pays for half the cost of raising a child. It cost $10,000 a year for the first 8 years and then twice that much per year until the child is 18. University tuition then costs $250,000. How much did it cost? How much did the first 8 years cost? ** The first 8 years cost 8*10,000=$<<8*10000=80000>>80,000 How much did the next 10 years cost? ** The next 18-8=<<18-8=10>>10 years How much did the next 10 years cost? ** They cost 10000*2=$<<10000*2=20000>>20,000 per year How much did the next 10 years cost? ** So they cost 20,000*10=$<<20000*10=200000>>200,000 How much did it cost? ** So the cost was 200,000+80,000=$<<200000+80000=280000>>280,000 How much did it cost? ** Adding in the cost of tuition brings the cost to 250,000+280,000=$<<250000+280000=530000>>530,000 How much did John pay? ** Since John pays for half the cost of raising the child, he pays $530000/2 = <<530000/2=265000>>265000 #### 265000 At a gym, the blue weights are 2 pounds each, and the green weights are 3 pounds each. Harry put 4 blue weights and 5 green weights onto a metal bar. The bar itself weighs 2 pounds. What is the total amount of weight, in pounds, of Harry's custom creation? How many pounds do all the blue weights weigh? ** The blue weights weigh 4*2=<<4*2=8>>8 pounds How many pounds do all the green weights weigh? ** The green weights weigh 5*3=<<5*3=15>>15 pounds How many pounds do all the weights weigh? ** The weights weigh 8+15=<<8+15=23>>23 pounds. What is the total amount of weight, in pounds, of Harry's custom creation? ** The total is then 23+2=<<23+2=25>>25. #### 25 Cindy tosses 5 dimes into the wishing pond. Eric flips 3 quarters into the pond. Garrick throws in 8 nickels. Ivy then drops 60 pennies in. If Eric dips his hands into the water and pulls out a quarter, how much money, in cents, did they put into the pond? How much money does Cindy put in? ** Cindy puts in 10 cents x 5 = <<10*5=50>>50 cents. How much money does Eric put in? ** Eric puts in 3 x 25 cents = <<3*25=75>>75 cents. How much money does Garrick put in? ** Garrick puts in 8 x 5 cents = <<8*5=40>>40 cents. How much money does Ivy put in? ** Ivy puts in 60 x 1 cent = <<60*1=60>>60 cents. How much money does Eric have left after pulling out a quarter? ** After Eric pulls out a quarter, he has still left in the pond, 75 - 25 = <<75-25=50>>50 cents. How much money did they put into the pond? ** Together, they put into the pond, this amount of money, 50 + 50 + 40 + 60 = <<50+50+40+60=200>>200 cents #### 200 Anthony and his friend Leonel read about the importance of keeping pets at home and decided to start adopting cats and dogs from the local rescue center. Anthony has 12 cats and dogs, 2/3 of which are cats. Leonel has half times as many cats as Anthony and seven more dogs than Anthony. How many animals in total do the two have? How many cats does Anthony have? ** If Anthony has 12 pets, the number of cats is 2/3 * 12 pets = <<12*2/3=8>>8 cats How many dogs does Anthony have? ** The number of dogs that Anthony have is 12 pets - 8 cats = <<12-8=4>>4 dogs How many cats does Leonel have? ** Leonel has 1/2 * 8 cats = <<8*1/2=4>>4 cats. How many dogs does Leonel have? ** If Leonel has seven more dogs than Anthony, then he has 4 dogs + 7 dogs = <<7+4=11>>11 dogs How many animals in total do the two have? ** The total number of pets the two have is 11 dogs for Leonel + 4 cats for Leonel + 4 dogs for Anthony + 8 cats for Anthony = <<11+4+4+8=27>>27 #### 27 Steve wanted to make a total of $100 within four days, so he took on a berry-picking job in Sweden. The job paid $2 for every pound of lingonberries picked. On Monday he picked 8 pounds. Tuesday’s harvest was triple what he had picked the previous day. On Wednesday he felt very tired and decided to rest. How many pounds of lingonberries did Steve have to pick on Thursday? How much did Steve make on Monday? ** On Monday, Steve was paid 8 * 2 = <<8*2=16>>16 dollars How many pounds did Steve pick on Tuesday? ** Tuesday’s harvest was 3 * 8 = <<3*8=24>>24 pounds How much did Steve make on Tuesday? ** The 24 pounds Steve picked on Tuesday gave him 24 * 2 = <<24*2=48>>48 dollars How much did Steve make on the first two days? ** So, the amount Steve earned from the first two days on the job is 16 +48 = <<16+48=64>>64 dollars How much did Steve make on the first three days? ** Since Steve rested on Wednesday, he made 0 dollars, meaning his earnings were 64 + 0 = <<64+0=64>>64 dollars How much did Steve miss his target by? ** The difference between Steve’s earnings and his target is 100 - 64 = <<100-64=36>>36 dollars How many pounds of lingonberries did Steve need to pick on Thursday? ** Since he was paid 2 dollars for each pound of lingonberries, Steve needed to pick 36/2 = <<36/2=18>>18 pounds #### 18 Bert was able to sell 8 toy phones for $18 each, while Tory was able to sell 7 toy guns for $20 each. How much more did Bert earn than Tory? How much did Bert earn from selling the toy phones? ** Bert was able to earn 8 x $18 = $<<8*18=144>>144 for the toy phones. How much did Tory earn from selling the toy guns? ** While Tory was able to earn 7 x $20 = $<<7*20=140>>140 for the toy guns. How much more did Bert earn than Tory? ** Therefore, Bert was able to earn $144 – $140 = $<<144-140=4>>4 more than Tory. #### 4 Pauline will make tacos for dinner. She bought a box of taco shells that cost $5, 4 bell peppers that cost $1.5 each, and 2 pounds of meat that cost $3 per pound. How much did she spend in all? How much did the bell peppers cost? ** She spent 4 x $1.5 = $<<4*1.5=6>>6 for the four bell peppers. How much did the meat cost? ** She spent 2 x $3 = $<<2*3=6>>6 for the 2 pounds of meat. How much did Pauline spend in all? ** So, Pauline spent $5 + $6 + $6 = $<<5+6+6=17>>17 in all. #### 17 A package of candy has 3 servings with 120 calories each. John eats half the package. How many calories did he eat? How many calories were in the package? ** There were 3*120=<<3*120=360>>360 calories in the package How many calories did John eat? ** So he ate 360/2=<<360/2=180>>180 calories #### 180 Diane bought twenty more apples than Cecile. If Cecile bought 15 apples, how many apples did they buy altogether? How many apples did Diane buy? ** Diane bought 15 + 20 = <<15+20=35>>35 apples. How many apples did they buy altogether? ** Therefore, they bought 15 + 35 = <<15+35=50>>50 apples altogether. #### 50
