The bedroom set is $2000 and it's currently 15% off so 2000 * .15 = $300.00 off. So the new price of the set is 2000 - 300 = $1,700.00. He signs up for the credit card so that's 10% off so .10 * 1700 = $170.00. Now the set is 1700 - 170 = $1,530.00. He has a $200.00 gift card which brings the price to 1530 - 200 = $1,330.00.
The answer: 1330
Reverse engineering the question: Perry wants to buy a new modern bedroom set for $2000. He received $200.00 in gift cards over the holidays that he can use toward the set. The store is currently offering the entire set at 15% off. If he signs up for the store credit card and uses it to buy the set, he will save an additional 10% off on the discounted set. What is the final price of the set?
Reasoning and answer: The computer and printer cost 400 + 40 = 440 dollars. Delores has 450 - 440 = 10 dollars left.
The answer: 10

Question: Delores has $450. She buys a computer for $400 and a printer for $40. How much money, in dollars, does Delores have left?
Adding the pizzas delivered in the park and in the building, Jimmy delivered a total of 2 + 3 = 5 pizzas. The value of the 5 pizzas without delivery charge is 5 pizzas * $12 / pizza = $60. The cost of the delivery charge for two pizzas is 2 pizzas * $2 / pizza = $4. In total, Jimmy got paid $60 + $4 = $64 for the pizzas.
The answer: 64
Reverse engineering the question: Jimmy is a pizza delivery man. Each pizza costs 12 dollars and the delivery charge is 2 extra dollars if the area is farther than 1 km from the pizzeria. Jimmy delivers 3 pizzas in the park, which is located 100 meters away from the pizzeria. Also, he delivers 2 pizzas in a building 2 km away from the pizzeria. How much money did Jimmy get paid for the pizzas?
Reasoning and answer: He still has to improve by 60 more seconds because 90 - 30 = 60. This will take 6 days because 60 / 10 = 6.
The answer: 6

Question: Chris wants to hold his breath underwater for 90 straight seconds so he starts training each day. On the first day, he holds it for 10 seconds. On the second day, he holds it for 20 seconds. On the third day, he holds it for 30 seconds. After realizing that he can hold it for ten extra seconds each day, he realizes he can calculate how many days it is until he reaches 90 if he keeps up the same pace. So how many days until he can hold his breath for 90 seconds?
Ten sandwiches every day for one week is 7 * 10 = 70 sandwiches. For every sandwich that Sam eats, he eats four apples, and since he ate 70 sandwiches, he ate 70 * 4 = 280 apples.
The answer: 280
Reverse engineering the question: For every sandwich that he eats, Sam eats four apples. If he eats 10 sandwiches every day for one week, how many apples does he eat?
Martha's car gets 20 / 2 = 10 miles per gallon. Total gallons Martha's car requires is 300 / 10 = 30 gallons.
The answer: 30
Reverse engineering the question:
Darlene's car gets 20 miles/gallon. Martha's car gets half as many miles per gallon as Darlene's car. How many gallons does Martha's car require to make a 300-mile trip?
