Consider the Q and A. Q: James can buy a new computer for $600 and have it last 6 years, or buy 2 used computers for $200 each that each last 3 years. How much money will he save by picking the cheaper option?
A: 200
What is the step-by-step reasoning process?
Step-by-step reasoning process: First find the cost of the two used computers: $200 / computer * 2 computers = $400. Then subtract that cost from the cost of the new computer to find the savings: $600 - $400 = $200.

Consider the Q and A. Q: There are 12 crates that each contain 150 oranges. There are 16 boxes that each hold 30 nectarines. How many pieces of fruit are in the crates and the boxes in total?
A: 2280
What is the step-by-step reasoning process?
Step-by-step reasoning process: Oranges = 12 * 150 = 1800. Nectarines = 16 * 30 = 480. 1800 + 480 = 2280. There are 2280 pieces of fruit in total.

Consider the Q and A. Q: When Harriett vacuumed the sofa and chair she found 10 quarters, 3 dimes, 3 nickels, and 5 pennies. How much money did Harriett find?
A: 3
What is the step-by-step reasoning process?
Step-by-step reasoning process: She found 10 quarters that are $0.25 each so she found 10 * .25 = $2.50. She found 3 dimes that are $0.10 each so she found 3 * .10 = $0.30. She found 3 nickels that are $0.05 each so she found 3 * .05 = $0.15. She found 5 pennies that are $0.01 each so she found 5 * .01 = $0.05. All total she found 2.50 + .30 + .15 + .05 = $3.00 in change.

Consider the Q and A. Q: Cindy was 5 years old. Her sister Jan was 2 years older than Cindy. Their oldest sister Marcia was twice as old as Jan. Greg was two years older than Marcia. How old was Greg?
A: 16
What is the step-by-step reasoning process?
Step-by-step reasoning process:
Jan was 2 years older than Cindy who was 5 so 2 + 5 = 7 years old. Marica was twice as old as Jan so 2 * 7 = 14 years old. Greg was 2 years older than Marcia who was 14 so 2 + 14 = 16 years old.
