Reasoning and answer: Since a dozen has 12 items, a half dozen has 1 / 2 * 12 = 6 items. Since Jamal bought four half dozen colored crayons, he bought 4 * 6 = 24 colored crayons. If each crayon's cost was $2, Jamal paid $2 * 24 = $48 for all the crayons he bought.
The answer: 48
What was the question?
Question: Jamal bought 4 half dozen colored crayons at $2 per crayon. What was the total cost of the crayons that she bought?

Reasoning and answer: Uki earns 20 x $1.50 = $30 in selling 20 cupcakes. She earns 10 x $2 = $20 for selling 10 packets of cookies,. Additionally, she earns another 20 x $1 = $20 for selling twenty packets of biscuits. Thus, in a day, she earns an average of $30 + $20 + $20 = $70.                                    Therefore, for five days, Uki earns 5 x $70 = $350. ".

There are four sides to a rectangle, the width is W and so the length is 2W, and we can put that in this equation: W + W + 2W + 2W = 30 feet. If we add the sides together, we get 6W = 30 feet. To find W, we divide both sides by 6, like this: 6W / 6 = 30 feet / 6, so W = 5 feet.
The answer: 5
