Q: Graeme is weighing cookies to see how many he can fit in his box. His box can only hold 40 pounds of cookies. If each cookie weighs 2 ounces, how many cookies can he fit in the box?
A: First find how many cookies are in a pound. 16 ounces per pound / 2 ounces / cookie = 8 cookies per pound. The box can hold 40 pounds, so 40 pounds * 8 cookies per pound = 320 cookies. The answer is 320.
Question: Each member of Greg’s softball team needs to buy one uniform made up of a shirt, a pair of pants, and socks. A shirt costs $7.50, a pair of pants cost $15, and socks cost $4.50 each if each team member buys the uniform items on their own. If they buy the items as a group, they are given a discount. A discounted shirt cost $6.75, a discounted pair of pants cost $13.50, and discounted socks cost $3.75. How much would their team of 12 save with the group discount?
Answer: The cost of a regularly - priced uniform is $7.50 for the shirt + $15 for pants + $4.50 for socks = $27. The cost of a discounted uniform is $6.75 for the shirt + $13.50 for pants + $3.75 for socks = $24. By purchasing the discounted uniform, each team member would save $27 for full price - $24 for discounted = $3. So, for the team of 12, they would save $3 * 12 = $36. The answer is 36.
