Answer the following question.
Jenna is planning a road trip. She plans on driving the first 200 miles, and her friend will drive the last 100 miles. They plan on taking 2 30-minute breaks. If Jenna drives 50 miles per hour and her friend drives 20 miles per hour, how many hours will they spend on the road trip?
Step-by-step reasoning process: Jenna will drive 200 miles at a rate of 50 miles per hour, so she will drive for 4 hours. Her friend will drive 100 miles at a rate of 20 miles per hour, so Jenna's friend will drive for 5 hours. They will spend a total of 60 minutes on breaks because 30 minutes + 30 minutes = 60 minutes. Thus, they will spend 1 hour on breaks because there are 60 minutes in an hour. The road trip will take a total of 1 + 4 + 5 = 10 hours.
The answer is 10.

Answer the following question.
A supermarket receives a delivery of 15 cases of tins of beans. Each case contains 24 tins. If 5% of the tins are damaged and thrown away, how many tins of beans are left?
Step-by-step reasoning process: The supermarket has 15 cases × 24 tins / case = 360 tins of beans delivered to them. There are 360 tins × 0.05 = 18 tins that are damaged and unsellable. So in the end, there are 360 tins - 18 tins = 342 tins of beans that are left.
The answer is 342.

Answer the following question.
Thomas started saving for a car almost 2 years ago. For the first year, his weekly allowance was $50. In the second year, he got a job that pays $9 an hour at a coffee shop and worked 30 hours a week, so his parents discontinued his allowance. If the car he wants to buy is $15,000 and he spends $35 a week on himself, how much more money does Thomas need to buy the car by the end of the 2 years?
Step-by-step reasoning process: There are 52 weeks in a year. For the first year, Thomas received 52 x 50 = $2600. In the second year, Thomas earned 9 x 30 = $270 a week. In a year, Thomas earned 52 x 270 = $14,040. The total for the two years is 14040 + 2600 = 16640. In 2 years, Thomas' weekly expenses amounted to $35 x (52 x 2) = $35 x 104 = $3640. By the end of 2 years, Thomas would have saved $16640 - $3640 = 13000. Thomas still needs $15,000 - 13000 = $2000.
The answer is 2000.
