Wendy's dentist bill was 5 * $120 = $600. She got two fillings at a cost of 2 * $120 = $240. Thus, Wendy paid $600 - $240 - $70 = $290 for the tooth extraction.
The answer: 290
Reverse engineering the question: Wendy went to the dentist for a cleaning, two fillings, and a tooth extraction. The dentist charges $70 for a cleaning and $120 for a filling. Wendy's dentist bill was five times the cost of a filling. What did Wendy pay for the tooth extraction?
Reasoning and answer: He now runs 3 + 2 = 5 times a week. Each day he runs for 1 + 1 = 2 hours. So he runs 2 * 5 = 10 hours a week.
The answer: 10
What was the question?
Question: Tim used to run 3 times a week but decided to add an extra 2 days a week. She runs 1 hour in the morning and 1 in the evening every day she runs. How many hours a week does she run now?
Malik = 18 * 4 = 72 yards. Josiah = 22 * 4 = 88. Darnell = 11 * 4 = 44 yards. Total yards = 72 + 88 + 44 = 204 yards. The 3 athletes ran 204 yards.
The answer: 204
Reverse engineering the question: Malik rushed for 18 yards in each of 4 games. Josiah ran for 22 yards in each of 4 games. Darnell had an average of 11 yards rushed for each of the 4 games. How many yards did the 3 athletes run in total?
Reasoning and answer: Officer A patrols 36 streets / 4 hours = 9 streets / hour. Officer B patrols 55 streets / 5 hours = 11 streets / hour. Together officer A and B patrol 9 streets / hour + 11 streets / hour = 20 streets / hour.
The answer: 20
What was the question?
Question: Police officer A patrols 36 streets in 4 hours. His colleague, officer B, patrols 55 streets in 5 hours. How many streets will both officers patrol in one hour?
Muffy weighs 12 - 3 = 9 ounces. Puffy weighs 5 + 9 = 14 ounces. If Brittany weighs both Puffy and Muffy, the scale would read 9 + 14 = 23 ounces.
The answer: 23
Reverse engineering the question: Brittany has 3 gerbils: Puffy, Muffy, and Scruffy. Puffy weighs 5 ounces more than Muffy. Muffy weighs 3 ounces less than Scruffy. If Scruffy weighs 12 ounces, how much would the scale indicate, in ounces, if Brittany put Puffy and Muffy on the scale?
Arthur spent 4 / 5 * $200 = $160. Thus he has $200 - $160 = $40 remaining.
The answer: 40
Reverse engineering the question:
Arthur has $200 in his wallet. He spends four-fifths of that. How much does he have left?
