Question: Jamal bought 4 half dozen colored crayons at $2 per crayon. What was the total cost of the crayons that she bought?

Q: Uki owns a bakery. She sells cupcakes at $1.50 each, cookies at $2 per packet, and biscuits at $1 per packet. In a day, she can bake an average of twenty cupcakes, ten packets of cookies, and twenty packets of biscuits. How much will be her total earnings for five days?

Question: Josh built his little brother a rectangular sandbox. The perimeter of the sandbox is 30 feet and the length is twice the width. What is the width of the sandbox?
Answer: 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 is 5.
