Maddie wants to see how much her mom spends on coffee each week. She makes herself 2 cups of coffee per day. Each cup has 1.5 ounces of coffee beans. A bag of coffee costs $8 and contains 10.5 ounces of beans. She uses 1/2 a gallon of milk per week. A gallon of milk costs $4. She doesn't add any sugar to the coffee. How much does she spend on her coffee per week?
How many ounces of beans does she use each day? ** She uses 3 ounces of beans per day because 2 x 1.5 =
<<2*1.5=3>>3 How many ounces of beans does she use each week? ** She uses 21 ounces of beans per week because 7 x 3 = <<7*3=21>>21 How many bags of beans does she buy each week? ** She buys 2 bags of beans per week because 21 / 10.5 = <<21/10.5=2>>2 How much does she spend on the beans each week? ** She spends $16 on the beans per week because 2 x 8 = <<16=16>>16 How much does she spend on the milk each week? ** She spends $2 on the milk per week because 4 x (1/2) = <<4*(1/2)=2>>2 How much does she spend on her coffee each week? ** She spends $18 per week on her coffee because 16 + 2 = <<16+2=18>>18 #### 18 On Sunday Trey is going to do some chores at home. First, he wants to make a To Do list and count up how many things he has to do that day and how long it should take. He has several items under 'clean the house,' 'take a shower' and then 'make dinner.' In total there are 7 things to do to clean the house; 1 thing to do to take a shower; and 4 things to do to make dinner. If everything on Trey's list takes 10 minutes to do, how many hours total will it take to complete Trey's list? How many things are on Trey's list? ** On Trey's list there are 7 + 1 + 4 things to do = <<7+1+4=12>>12 things to do in total. How many minutes are in Trey's list? ** Each thing takes 10 minutes to do, so 10 minutes x 12 things = <<10*12=120>>120 minutes. How many hours total will it take to complete Trey's list? ** An hour has 60 minutes in it, so 120 minutes / 60 minutes in an hour = <<120/60=2>>2 total hours it will take Trey to complete his list. #### 2 James decides to build a tin house by collecting 500 tins in a week. On the first day, he collects 50 tins. On the second day, he manages to collect 3 times that number. On the third day, he collects 50 tins fewer than the number he collected on the second day. If he collects an equal number of tins on the remaining days of the week, what's the number of tins he collected each day for the rest of the week? How many tins did James collect on the second day? ** On the second day, he collected 3 times the number of tins he collected on the first day, which is 3*50 = <<3*50=150>>150 tins. How many tins did James collect on the third day? ** On the third day, he collected 50 tins fewer than the second day, which is 150-50 = <<150-50=100>>100 tins How many tins did James collect in the first three days? ** The total for the three days is 150+100+50 = <<150+100+50=300>>300 tins. How many tins does James need to collect? ** To reach his goal, he still needs 500-300 = <<500-300=200>>200 tins. How many tins does James need to collect each day? ** Since the total number of days left in the week is 4, he'll need to collect 200/4 = <<200/4=50>>50 tins per day to reach his goal #### 50 James goes out to eat. He orders a steak and egg meal for $16. He is with his friend, who orders chicken fried steak for $14. His friend pays for half the bill and James pays the tip along with his half of the bill. They tip 20%. How much did James pay? How much did the meals cost? ** The meals cost 16+14=$<<16+14=30>>30 How much did each pay? ** So each paid 30/2=$<<30/2=15>>15 How much did James leave as a tip? ** James left a tip of 30*.2=$<<30*.2=6>>6 How much did James pay? ** So James paid 15+6=$<<15+6=21>>21 #### 21 Sammy can eat 15 pickle slices. His twin sister Tammy can eat twice as much as Sammy. Their older brother Ron eats 20% fewer pickles slices than Tammy. How many pickle slices does Ron eat? How many pickle slices does Tammy eat? ** Tammy can eat twice as many pickle slices as Sammy who eats 15 so Tammy can eat 15*2 = <<15*2=30>>30 pickle slices How many pickle slices does Ron eat? ** Ron eats 20% fewer pickle slices than Tammy who eats 30 pickle slices so that's .20*30 = <<20*.01*30=6>>6 fewer slices than Tammy How many pickle slices does Ron eat? ** Tammy eats 30 slices and Ron eats 6 less, then Ron eats 30-6 = <<30-6=24>>24 pickle slices #### 24 Cupcakes are sold in packages of 10 and 15. Jean bought 4 packs of 15 cupcakes. If she will give one cupcake each to 100 children in the orphanage, how many packs of 10 cupcakes should she need to buy? How many cupcakes did Jean buy? ** Jean already bought 15 cupcakes x 4 packs = <<15*4=60>>60 cupcakes. How many more cupcakes does Jean need? ** She needs 100 - 60 = <<100-60=40>>40 more cupcakes. How many packs of 10 cupcakes does Jean need to buy? ** Thus, she needs to buy 40/10 = <<40/10=4>>4 packs of 10 cupcakes. #### 4 At the beginning of the day there were 74 apples in a basket. If Ricki removes 14 apples and Samson removes twice as many as Ricki. How many apples are left in the basket by the end of the day? How many apples are left after Ricki removes some? ** There are 74-14 = <<74-14=60>>60 apples left after Ricki removes some. How many apples does Samson remove? ** Samson removes 14*2 = <<14*2=28>>28 apples. How many apples are left in the basket by the end of the day? ** There are 60-28 = <<60-28=32>>32 apples left after Samson removes some. #### 32 A school has 15 classrooms. One-third of these classrooms have 30 desks in each classroom and the rest have 25 desks in each classroom. Only one student can sit at one desk. How many students can this school accommodate so that everyone has their own desk? How many classrooms have 30 desks? ** One-third of the classrooms have 30 desks, so there are 1/3 * 15 = <<1/3*15=5>>5 classrooms like that. How many classrooms have 25 desks? ** The rest, which means 15 - 5 = <<15-5=10>>10 classrooms, have 25 desks. How many students can one-third of the classrooms accommodate? ** One-third of the classrooms can fit 5 * 30 = <<5*30=150>>150 students. How many students can the rest of the classrooms accommodate? ** The rest can fit 10 * 25 = <<10*25=250>>250 students. How many students can the school accommodate? ** So in total, the school can be filled with 150 + 250 = <<150+250=400>>400 students. #### 400 James decides to buy a new bed and bed frame. The bed frame is $75 and the bed is 10 times that price. He gets a deal for 20% off. How much does he pay for everything? How much does the bed cost? ** The bed cost 75*10=$<<75*10=750>>750 How much does everything cost? ** So everything cost 750+75=$<<750+75=825>>825 How much does he get off? ** He gets 825*.2=$<<825*.2=165>>165 off How much does he pay? ** So that means he pays 825-165=$<<825-165=660>>660 #### 660 James takes 20 units per semester at community college. If each unit costs $50 how much does he pay for 2 semesters? How much does James pay for each semester? ** He pays 20*50=$<<20*50=1000>>1000 per semester How much does James pay for 2 semesters? ** So he pays 1000*2=$<<1000*2=2000>>2000 #### 2000
