Erin works in the school cafeteria serving soup. Each bowl of soup has 10 ounces, and Erin can serve 5 bowls per minute. If the pot of soup has 6 gallons of soup, how long will it take Erin to serve all the soup, rounded to the nearest minute? (There are 128 ounces to a gallon.)

First find the number of ounces Erin serves per minute: 10 ounces/bowl * 5 bowls/minute =

<<10*5=50>>50 ounces/minute Then find the number of ounces in the pot: 6 gallons * 128 ounces/gallon = <<6*128=768>>768 ounces Then divide the total amount of soup by the amount of soup Erin serves per minute: 768 minutes / 50 ounces/minute = <<768/50=15.36>>15.36 minutes, which rounds down to 15 minutes #### 15 A carpenter is building a house. He needs 80 woodblocks to build it. If he has 8 logs that can make five woodblocks each, how many logs does the carpenter still need? The carpenter initially has 8 x 5 = <<8*5=40>>40 blocks of wood. So he still lacks 80 - 40 = <<80-40=40>>40 blocks of wood. Therefore he still needs 40 / 5 = <<40/5=8>>8 logs of wood. #### 8 Brian is a real estate agent. He makes a 2% commission on each sale. During June, he sold three houses. The houses sold for $157,000, $499,000, and $125,000. What was Brian’s total commission on these three sales? Brian sold houses for 157,000 + 499,000 + 125,000 = $<<157000+499000+125000=781000>>781,000 in total. Brian's commission was 781,000 * 0.02 = $<<781000*0.02=15620>>15,620 #### 15,620 Justin bought some jerseys. He bought four long-sleeved ones that cost $15 each, and some striped ones that cost $10 each. How many striped jerseys did Justin buy if he spent a total of $80? Four long-sleeved jerseys cost $15 x 4 = $<<15*4=60>>60. So the striped jerseys amount to $80 - $60 = $<<80-60=20>>20. Hence, Justin bought $20/$10= <<20/10=2>>2 striped jerseys. #### 2 Hazel walked 2 kilometers in the first hour. If she walked twice as far in the second hour, how far did she walk for 2 hours? Hazel walked 2 x 2 = <<2*2=4>>4 kilometers in the second hour. So, she walked 2 + 4 = <<2+4=6>>6 kilometers for 2 hours. #### 6 Oranges have 80 calories and cost $1.20 each. If Timmy has $10 and needs to make sure he gets 400 calories, how much money will he have left after he buys the oranges he needs? He needs to buy 5 oranges because 400 / 80 = <<400/80=5>>5 These will cost $6 because 5 x 1.2 = <<5*1.2=6>>6 He will have $4 left because 10 - 6 = <<10-6=4>>4 #### 4 There are 78 pieces of fruit in a crate. One-third of the box contains kiwi. The rest are strawberries. How many strawberries are there? One-third of the fruit: 78/3 = <<78/3=26>>26 kiwis The rest are strawberries: 78 - 26 = <<78-26=52>>52 There are 52 strawberries in the crate. #### 52 Stacy has 2 more than triple as many berries as Steve. Steve has one half as many berries as Skylar. If Skylar has 20 berries, how many berries does Stacy have? Steve has (1/2)(20)=10 berries Stacy has 2+3(10)=32 berries #### 32 Ron is part of a book club that allows each member to take a turn picking a new book every week. The club is made up of three couples and five single people along with Ron and his wife. How many times a year does Ron get to pick a new book? There are 3 couples in the club, so there are 3 * 2 = <<3*2=6>>6 people in couples in the club. Along with the singles and Ron and his wife, there are 6 + 5 + 2 = <<6+5+2=13>>13 people in the book club. There are 52 weeks in a year, so Ron gets to pick a new book 52 / 13 = <<52/13=4>>4 times a year. #### 4 Alice and Bob decided to bake cookies for their first date. Alice baked 74 chocolate chip cookies and Bob baked 7 peanut butter cookies. After accidentally throwing some on the floor, Alice baked 5 more cookies and Bob baked 36 more. If they had 93 edible cookies at the end, how many were accidentally thrown on the floor? Before throwing the cookies, Alice and Bob baked 74 + 7 = <<74+7=81>>81 cookies. After throwing the cookies, they baked 5 + 36 = <<5+36=41>>41 cookies. In total, they baked 81 + 41 = <<81+41=122>>122 cookies They threw 122 - 93 = <<122-93=29>>29 cookies on the floor. #### 29
