Luna, the poodle, is supposed to eat 2 cups of kibble every day. But Luna's master, Mary, and her husband, Frank, sometimes feed Luna too much kibble. One day, starting with a new, 12-cup bag of kibble, Mary gave Luna 1 cup of kibble in the morning and 1 cup of kibble in the evening, But on the same day, Frank also gave Luna 1 cup of kibble in the afternoon and twice as much in the late evening as he had given Luna in the afternoon. The next morning, how many cups of kibble will Mary find remaining in the bag?

How many cups of kibble did Mary give Luna? ** Mary fed Luna 1+1=2 cups of kibble.

How many cups of kibble did Frank give Luna? ** Frank fed Luna 1-cup plus twice 1-cup, or 1+2=3 cups of kibble.

How many cups of kibble did Mary and Frank give Luna? ** In total, they fed Luna 2+3=

<<2+3=5>>5 cups of kibble. How many cups of kibble will Mary find remaining in the bag? ** Thus, if the new bag held 12 cups of kibble, the next morning, 12-5=<<12-5=7>>7 cups of kibble remained in the bag. #### 7 Faith went to a baking shop and bought flour that cost $5 and a cake stand that costs $28. She then gave the cashier two $20 bills and $3 in loose coins. How much change will she receive? How much does the flour and cake stand cost? ** Faith must pay $28 + $5 = $<<28+5=33>>33 for the flour and cake stand. How much do the two $20 bills cost? ** Her two $20 bills amount to $20 x 2 = $<<20*2=40>>40. How much did Faith give the cashier? ** So, she gave the cashier a total of $40 + $3 = $<<40+3=43>>43. How much change will she receive? ** Hence, her change is $43 - $33 = $<<43-33=10>>10. #### 10 Tom wants to make the world's largest dough ball. He needs 500 pounds of flour and he can buy 50-pound bags of flour for $20. He also needs 10 pounds of salt and salt cost $.2 a pound. He also spends $1000 promoting everything. He then sells tickets for $20 each and sells 500 tickets. How much money did he make? How many bags of flour does Tom need? ** He needs 500/50=<<500/50=10>>10 bags of flour How much did the bags of flour cost? ** That cost 20*10=$<<20*10=200>>200 How much salt does Tom need? ** He needs 10*.2=$<<10*.2=2>>2 worth of salt How much did Tom spend? ** So everything cost 1000+200+2=$<<1000+200+2=1202>>1202 How much money did Tom make? ** He makes 20*500=$<<20*500=10000>>10,000 selling tickets How much money did Tom make? ** So he makes a profit of 10000-1202=$<<10000-1202=8798>>8798 #### 8798 Susan wants to throw a party for her mom. She is planning on having 30 guests. For dinner she is making a recipe that makes 2 servings each. Each batch of the recipe calls for 4 potatoes and 1 teaspoon of salt. A potato costs $.10 and a container of salt costs $2 at the supermarket. If each container of salt has 5 teaspoons, how much money will Susan spend on food? How many batches of the recipe does Susan need to make? ** Susan needs to make 30/2=<<30/2=15>>15 batches of the recipe. How many potatoes does Susan need? ** Therefore, she will need 15*4=<<15*4=60>>60 potatoes. How many teaspoons of salt does Susan need? ** She will also need 1*15=<<1*15=15>>15 teaspoons of salt. How many containers of salt will Susan buy? ** Thus she will have to buy 15/5 =<<15/5=3>>3 containers of salt. How much money will Susan spend on potatoes and salt? ** Therefore, she will spend 60*$.1=$6 on potatoes and 3*$2=$6 on salt. How much money will Susan spend on food? ** Thus, she will spend $6+$6=$<<6+6=12>>12 on food. #### 12 Joan is at the grocery store. She has a total of $60 to spend. She is going to purchase 2 containers of hummus, which are $5 each. She is going to purchase chicken for $20, bacon for $10, and vegetables for $10. She wants to purchase apples which are $2 each. With her remaining money, how many apples can she purchase? How much are the hummus containers? ** The total cost of the hummus is 2 * $5 = $<<2*5=10>>10 How much are the chicken, bacon, and vegetables? ** The total cost of the chicken, bacon, and vegetables is $20 + $10 + $10 = $<<20+10+10=40>>40 How much money does Joan have left? ** The remaining money she has is $60 - $10 - $40 = $<<60-10-40=10>>10 How many apples can Joan purchase? ** The amount of apples she can purchase is $10 / $2 = <<10/2=5>>5 #### 5 Lenny bought 20 boxes of pens. Each box contained 5 pens. She gave 40% of the pens to her close friends and one-fourth of what's left to her classmates. How many pens were left for Lenny? How many pens does Lenny have? ** Lenny has 20 x 5 = <<20*5=100>>100 pens. How many pens did Lenny give to her close friends? ** She gave her close friends 100 x 40% = <<100*40*.01=40>>40 pens. How many pens were left for Lenny? ** So, 100 - 40 = <<100-40=60>>60 pens were left. How many pens did Lenny give to her classmates? ** Half of 60 is 60/4= <<60/4=15>>15 pens. How many pens were left for Lenny? ** Thus, Lenny has 60 - 15 = <<60-15=45>>45 pens left. #### 45 Josh has 18 yards of ribbon that is to be used equally to 6 gifts. If each gift will use 2 yards of ribbon, how many yards of ribbon will be left? How many yards of ribbon will the 6 gifts use? ** The 6 gifts will use 6 x 2 = <<6*2=12>>12 yards of ribbon. How many yards of ribbon will be left? ** So, 18 - 12 = <<18-12=6>>6 yards of ribbon will be left. #### 6 A dietitian ate three-fourths of her lunch during her lunch break. If the total amount of food she had prepared for lunch had 40 calories, and the recommended calorie intake by the FDA is 25, how many more calories than the recommended amount did she eat? How many calories did the dietitian eat during her lunch break? ** A dietitian ate three-fourths of her lunch during her lunch break, containing 3/4*40=<<3/4*40=30>>30 calories. How many more calories than the recommended amount did the dietitian eat? ** If the recommended calorie intake by the FDA is 25, the dietitian ate 30-25=5 more calories than the recommended amount. #### 5 Brenda picks 250 peaches. When she sorts through them, only 60% are fresh, and Brenda has to throw 15 away for being too small. How many peaches does Brenda have left? How many peaches are fresh? ** First find how many of the peaches are fresh, which is 250 peaches * 60% = <<250*60*.01=150>>150 peaches. How many peaches does Brenda have left? ** Then, subtract the number Brenda throws away after the fresh count, which is 150 peaches - 15 peaches = <<150-15=135>>135 peaches. #### 135 Megan is delivering meals on wheels. Out of her 30 clients, 7 need vegan meals, 8 need kosher meals, and three people need meals that are both vegan and kosher. How many meals does Megan deliver that are neither kosher nor vegan? How many meals are vegan and kosher? ** First, add the number of kosher meals to the number of vegan meals: 7 meals + 8 meals = <<7+8=15>>15 meals How many meals are neither vegan nor kosher? ** Then subtract the three meals that are both kosher and vegan since they got counted twice: 15 meals - 3 meals = <<15-3=12>>12 meals How many meals are neither kosher nor vegan? ** Finally, subtract that number from the total number of meals to find the number of meals that are neither kosher nor vegan: 30 meals - 12 meals = <<30-12=18>>18 meals #### 18
