Q: In North Carolina, Jim bought 10 gallons of gas at $2.00/gallon. He paid $1.00 more per gallon in Virginia where he bought another 10 gallons of gas. How much has he spent on gas?
A: In North Carolina, he bought 10 gallons at $2.00 / gallon for a total of 10 * 2 = $20.00. He paid $2.00 a gallon in North Carolina and $1.00 more in Virginia for a total of 2 + 1 = $3.00 / gallon. He bought 10 gallons at $3.00 / gallon in Virginia for a total of 10 * 3 = $30.00. He spent $20.00 in North Carolina and $30.00 in Virginia for total of 20 + 30 = $50.00. The answer is 50.
Question: A man is purchasing a pair of sneakers at a club store where he receives a membership discount of 10% off any purchase. In addition to the membership discount, the man also has a coupon for $10 off any pair of sneakers. If the man wants to purchase a $120 pair of sneakers and the membership discount must be applied after the coupon, how much will he pay for the sneakers after using both the coupon and membership discount?
Answer: The coupon is applied first, which reduces the cost of the sneakers to 120 - 10 = $110. Next, the 10% discount leads to a reduction in price of 110 * 0.1 = $11. Therefore, the final price the man must pay is 110 - 11 = $99. The answer is 99.

Question: Wendi lives on a plot of land that is 200 feet by 900 feet of grassland. She raises rabbits on her property by allowing the rabbits to graze on the grass that grows on her land. If one rabbit can eat enough grass to clear ten square yards of lawn area per day, and Wendi owns 100 rabbits, how many days would it take for Wendi's rabbits to clear all the grass off of her grassland property?
Answer: One square yard is the same as 3 feet by 3 feet, or 3 * 3 = 9 square feet. Ten square yards is 9 * 10 = 90 square feet. Therefore, 100 rabbits can clear 100 * 90 = 9,000 square feet of grassland per day. A 200 ft by 900 ft area is 200 * 900 = 180,000 square feet. Thus, 180,000 sq ft can be cleared by 100 rabbits in 180,000 / 9000 = 20 days. The answer is 20.
Q: Kristy baked cookies because her friends are coming over to her house. She ate 2 of them and gave her brother 1 cookie. Her first friend arrived and took 3 cookies. The second and third friends to arrive took 5 cookies each. If there are 6 cookies left, how many cookies did Kristy bake?
A:
There were 6 + 5 = 11 cookies left before the third friend took 5. There were 11 + 5 = 16 cookies left before the second friend took 5. There were 16 + 3 = 19 cookies left before the first friend took 3. There were 19 + 1 = 20 cookies left before Kristy gave 1 cookie to her brother. There were 20 + 2 = 22 cookies that Kristy baked. The answer is 22.
