Q: Tomorrow, Pete must finish paying off the last $90 he owes on a bike. He goes through his wallet and finds two $20 bills. Checking his pockets, he finds four $10 bills. Unhappy that he doesn't have the entire amount, he suddenly remembers that he has plastic bottles that can be returned to his local store for cash. If the store pays 50 cents for each bottle, how many bottles will Pete have to return to the store?
A: 20
Step-by-step reasoning process: Pete's wallet contains 2 * 20 = 40 dollars. The money in Pete's pockets is 4 * 10 = 40 dollars. In total Pete has 40 + 40 = 80 dollars. He owes 90 dollars on the bike and therefore needs 90 - 80 = 10 more dollars. Since 50 cents is dollar, then the number of bottles required to get 10 dollars is 10 / (1 / 2) = 10 * 2 = 20 bottles.

Q: A car traveled 360 miles in 4 hours and 30 minutes. What was its speed in miles per hour?
A: 80
Step-by-step reasoning process: There are 60 minutes in one hour, so the car traveled 360 miles in 4 hours + 30 minutes / 60 minutes / hour = 4.5 hours. In one hour, the car travels 360 miles / 4.5 hours = 80 miles / hour.

Q: Jaden had 14 toy cars. Then he bought 28 cars from the toy store and got 12 cars for his birthday. Jaden gave 8 of the toy cars to his sister and 3 to his friend Vinnie. How many toy cars does Jaden have left?
A: 43
Step-by-step reasoning process: Jaden had a total of 14 cars + 28 cars = 42 cars after buying from the toy store. His total then increased to 42 cars + 12 cars = 54 cars on his birthday. Jaden then had 54 cars - 8 cars = 46 cars after giving 8 to his sister. Finally after giving his friend, Vinnie, a few cars Jaden had 46 cars - 3 cars = 43 cars left.

Q: Carter grew 9 plants with 3 seed packets. How many more seed packets does Carter need to have a total of 12 plants in his backyard?
A: 1
Step-by-step reasoning process: If he grows 9 plants with 3 seed packets, he grows 9 / 3 = 3 plants with 1 seed packet. Since 1 seed packet grows 3 plants, he'll need 1 more to make the plants 12.
