If 6 friends each want 2 bars, that's 6 friends * 2 bars = 12 bars needed. Each box contains 3 bars, so 12 bars / 3 bars per box = 4 boxes needed. A box is $7, so 4 boxes * $7.50 = $30. There are 6 friends so $30 / 6 friends = $5 per person.
The answer: 5
Reverse engineering the question: A box of ice cream bars costs $7.50 and contains three bars. 6 friends want to each eat 2 bars. How much money will that require per person?

If Lou runs 3 miles during his workout on a track that is 1 / 4 miles long, then he circles the track 3 / (1 / 4) = 12 times. If Rosie runs twice as fast as Lou, then over the same time period, she runs 3 * 2 = 6 miles. If Rosie runs 6 miles on the 1 / 4 mile track, then she circles the track 6 / (1 / 4) = 24 times.
The answer: 24
Reverse engineering the question: Every day, Lou works out by running three miles on a circular track that is one-quarter of a mile long. His wife, Rosie, also runs on the same track at the same time as her husband, but she runs at twice the speed of her husband. During their workout, how many times does Rosie circle the track?

Nancy has 40 + 20 = 60 pearl beads. So, Nancy has a total of 40 + 60 = 100 beads. Rose has 2 x 20 = 40 stone beads. So, Rose has 20 + 40 = 60 beads. Thus, Nancy and Rose have 100 + 60 = 160 beads altogether. Therefore, they can make 160 / 8 = 20 bracelets.
The answer: 20
Reverse engineering the question: Nancy and Rose are making bracelets, and there are eight beads in each bracelet. Nancy has 40 metal beads and 20 more pearl beads. Rose has 20 crystal beads and twice as many stone beads as crystal beads. How many bracelets can Nancy and Rose make?

Each of the 3 children gets 1 juice box, 5 days a week, so she needs 3 * 5 = 15 juice boxes in 1 week. The school year is 25 weeks long and she needs 15 juice boxes per week so she needs 25 * 15 = 375 juice boxes.
The answer: 375
Reverse engineering the question:
Peyton has 3 children and they each get a juice box in their lunch, 5 days a week. The school year is 25 weeks long. How many juices boxes will she need for the entire school year for all of her children?
