If Legacy has 5 bars, Aleena has 5 bars - 2 bars = 3 bars. In total, they have 5 bars + 3 bars = 8 bars,. Since one bar of gold is worth $2200, the 8 bars they have together are worth 8 bars * $2200 / bar = $17600.
The answer: 17600
Reverse engineering the question: Legacy has 5 bars of gold she received from her father. Her friend Aleena has 2 bars fewer than she has. If a bar of gold is worth $2200, calculate the total value of gold the three have together.

A round trip to work and back takes 2 * 2 = 4 hours. Ten times the time Kyle takes to travel to work and back is the same as the cost of buying a pack of snacks, meaning the packs are sold at 4 * 10 = $40 each. Ryan will pay $40 * 50 = $2000 to buy 50 packs of snacks?.
The answer: 2000
Reverse engineering the question: Kyle bikes for 2 hours to work every day. Ten times the time he takes to travel to work and back is the same as the cost of buying a pack of snacks (in dollars). How much will Ryan pay, in dollars, to buy 50 packs of snacks?

Both Polly and Peter played 30 / 2 = 15 moves each one. With an average of 28 seconds per move, Polly's moves lasted a total of 15 * 28 = 420 seconds. With an average of 40 seconds per move, Peter's moves lasted a total of 15 * 40 = 600 seconds. In total, the match lasted 420 + 600 = 1020 seconds. In minutes, the match lasted 1020 / 60 = 17 minutes.
The answer: 17
Reverse engineering the question: Polly and Peter play chess. Polly takes an average of 28 seconds per move, while Peter takes an average of 40 seconds per move. The match ends after 30 moves. How many minutes did the match last?

Two boxes of crayons have 24 x 5 / 8 = 15 unused crayons from each box. So, a total of 15 x 2 = 30 unused crayons are in the two boxes. For the other 2 boxes, there are 24 x 2 / 3 = 16 used crayons from each box. Hence, there are 24 - 16 = 8 unused crayons. So, a total of 8 x 2 = 16 unused crayons are in the other two boxes. Therefore, Madeline has a total of 30 + 16 + 24 = 70 unused crayons.
The answer: 70
Reverse engineering the question:
Madeline has 5 boxes with 24 crayons in each. She noticed that 5/8 of the crayons in the 2 boxes were not yet used. In the 2 other boxes, only 2/3 of the crayons were used while the last box was not entirely used. How many unused crayons did Madeline have?
