Q: Stormi is saving up to buy a bicycle. She washes 3 cars for $10 each. She mows 2 lawns for $13 each. If the bicycle she wants costs $80, how much more money does Stormi need to make to afford the bicycle?
A: The total amount of money from washing cars is 3 * $10 = $30. The total amount of money from mowing lawns 2 * $13 = $26. The total amount of money Stormi makes is $30 + $26 = $56. Stormi still needs to make $80 - $56 = $24. The answer is 24.
Question: Pete walks backwards three times faster than Susan walks forwards, and Tracy does one-handed cartwheels twice as fast as Susan walks forwards. But Pete can walk on his hands only one quarter the speed that Tracy can do cartwheels. If Pete walks on his hands at 2 miles per hour, how fast can Pete walk backwards, in miles per hour?
Answer: If Pete walks on hands at 1 / 4 what Tracy can do 1 - handed cartwheels, then Tracy can do 1 - handed cartwheels at 2 * 4 = 8 miles per hour. Since Tracy does 1 - handed cartwheels twice the rate of Susan's forward walking, then Susan walks at 8 / 2 = 4 miles per hour. Pete walks backwards 3x faster than Susan walks forward, and thus Pete walks backwards at 4 * 3 = 12 miles per hour. The answer is 12.
[Question]A rectangular flowerbed in the city park is 4 meters wide. Its length is 1 meter less than twice its width. The government wants to fence the flowerbed. How many meters of fence are needed?
[Answer]Twice the width is 4 x 2 = 8 meters. The length of the rectangular flowerbed is 8 - 1 = 7 meters. Since the rectangular flower bed has 2 equal lengths, then it needs 7 x 2 = 14 meters of fence. The rectangular bed has also 2 equal widths, so it needs 4 x 2 = 8 meters of fence. Therefore, the rectangular flower bed needs a total of 14 + 8 = 22 meters of fence. The answer is 22.
Q: Mama bird has 6 babies in the nest. She needs to feed each baby 3 worms a day. Papa bird caught 9 worms. If she caught 13 worms and had 2 stolen, how many more does she need to catch to feed them for 3 days?
A: Each day, mama bird needs to catch 6 x 3 = 18 worms. For 3 days, she needs 18 x 3 = 54 worms. She already has 13 - 2 = 11 worms. With papa bird’s catch, they have 11 + 9 = 20 worms. To feed the babies for 3 days, she needs to catch 54 - 20 = 34 more worms. The answer is 34.
Question: Mary wants to bake 10 apple pies for a charity event. Each pie needs 8 apples and she already harvested 50 apples from the trees in her garden. How many more apples does she need to buy to make all 10 pies?
Answer: She needs 10 * 8 = 80 apples to make the pies. So she has to buy 80 - 50 = 30 more apples. The answer is 30.

Let x be the amount of the discount. We have, 22 - x = $16. We change the writing of the equation:. 22 - x + x = 16 + x. So, 22 = 16 + x. We then Remove 16 from both sides:. 22 - 16 = 16 + x - 16. So, 22 - 16 = x. So, the amount of the discount is x = $6. The answer is 6.
