Bob ordered 80 packs of Greek yogurt from Costco to use for the month. However, when the delivery arrived, he realized 40% of the packs were expired. He decided to return those packs. If each pack was $12, how much was Bob refunded for the expired product?

The number of Greek yogurt packs that had expired is 40/100*80 =

<<40/100*80=32>>32 If each pack of Greek yogurt was sold at $12, for the 32 packs of greek yogurt that he returned, Bob was refunded $12*32 = $<<12*32=384>>384 #### 384 Jackie can do 5 push-ups in 10 seconds. How many push-ups can she do in one minute if she takes two 8-second breaks? There are 60 seconds per minute, so Jackie’s push-up routine takes 1 * 60 = <<60=60>>60 seconds. Her breaks last 2 * 8 = <<2*8=16>>16 seconds. She does push-ups for 60 - 16 = <<60-16=44>>44 seconds. She can do a push-up in 10 / 5 = <<10/5=2>>2 seconds. Therefore, Jackie can do 44 / 2 = <<44/2=22>>22 push-ups in one minute with breaks. #### 22 A box of six popsicles was left out in the sun and is slowly melting. Every time a popsicle melts the remaining popsicles melt twice as fast as the previous one. How many times faster than the first popsicle does the last popsicle’s remains melt? The remains of the second popsicle melt 2 * 1 = <<2*1=2>>2 times as fast as the first. The remains of the third popsicle melt 2 * 2 = <<2*2=4>>4 times as fast as the first. The remains of the fourth popsicle melt 2 * 4 = <<2*4=8>>8 times as fast as the first. The remains of the fifth popsicle melt 2 * 8 = 16 times as fast as the first. The remains of the sixth popsicle melt 2 * 16 = <<2*16=32>>32 times as fast as the first popsicle. #### 32 Alex had 36 ounces of jelly beans. He ate 6 ounces. Then he divided the rest equally into 3 piles. How much does each pile weigh? Start by taking out the ones he ate: 36 ounces - 6 ounces = <<36-6=30>>30 ounces. Divide the remainder equally: 30 ounces / 3 piles = <<30/3=10>>10 ounces per pile. #### 10 Samanta is planning a party for her friend Marta. She decided to raise some money among the guests she invited, to buy Marta a gift. Every participant gave Samanta $5 for this purpose and she herself put in $10. The gift cost was lower than expected, so there was $15 leftover. What was the price of the gift, if there were 12 guests invited? From all the guests Samanta got $5/guest * 12 guests = $<<5*12=60>>60. Including money Samanta put herself, she had $60 + $10 = $<<60+10=70>>70. The cost of the gift was $70 - $15 = $<<70-15=55>>55. #### 55 A father and a son start approaching each other at the same time from opposite ends of a hallway that is 16m long. If the father is walking three times as fast as the son, at what distance from the father's end of the hallway will they meet? Since the father is walking 3 times as fast as his son, their speeds are in a ratio of 3:1 respectively They started at the same time so they will cover distance at the same ratio of 3:1 Each portion of the distance they covered is 16/(3+1) = <<16/(3+1)=4>>4m The father covered three portions of the distance which is 3*4m = <<3*4=12>>12m from his end #### 12 Lightning McQueen, the race car, cost 140000$. Mater only cost 10 percent of that, and Sally McQueen cost triple what Mater costs. How much does Sally McQueen cost? Mater:140000(.10)=14000$ Sally:14000(3)=42000$ #### 42000 Liz bought a recipe book that cost $6, a baking dish that cost twice as much, five ingredients that cost $3 each, and an apron that cost a dollar more than the recipe book. Collectively, how much in dollars did Liz spend? The baking dish cost 6*2 = <<6*2=12>>12. The ingredients cost 5*3 = <<5*3=15>>15. The apron cost 6+1 = <<6+1=7>>7. Collectively, Liz spend 6+12+15+7 = <<6+12+15+7=40>>40 #### 40 There are 40 ducks in a pond. 50 percent of the ducks are Muscovy and 30 percent of the Muscovies are female. How many female Muscovy ducks there? Muscovies: 40(.50)=<<40*.50=20>>20 Muscovy ducks Female Muscovies:20(.30)=6 ducks #### 6 Kristy baked cookies because her friends are coming over to her house. She ate 2 of them and gave her brother 1 cookie. Her first friend arrived and took 3 cookies. The second and third friends to arrive took 5 cookies each. If there are 6 cookies left, how many cookies did Kristy bake? There were 6 + 5 = <<6+5=11>>11 cookies left before the third friend took 5. There were 11 + 5 = <<11+5=16>>16 cookies left before the second friend took 5. There were 16 + 3 = <<16+3=19>>19 cookies left before the first friend took 3. There were 19 + 1 = <<19+1=20>>20 cookies left before Kristy gave 1 cookie to her brother. There were 20 + 2 = <<20+2=22>>22 cookies that Kristy baked. #### 22
