Question: John drives 1000 miles a month. He needs to get an oil change every 3000 miles. He gets 1 free oil change a year. If an oil change costs $50, how much does he pay a year?
Answer: He needs to get an oil change every 3000 / 1000 = 3 months. So he gets 12 / 3 = 4 oil changes a year. That means he pays for 4 - 1 = 3 oil changes a year. So he pays 3 * $50 = $150 a year. The answer is 150.
[Question]A school bus traveled for 42 minutes at a speed of 50 mph. What is the distance the bus traveled in miles?
[Answer]1 hour = 60 minutes. We convert the time to hours, so 42 minutes = 42 / 60 hours = 7 / 10 hours. So in 42 minutes, the distance the bus traveled in miles is 50 * (7 / 10) = 35 miles. The answer is 35.
Q: Stephanie is checking her household budget, and needs to calculate how much she has left to pay for her bills. Her electricity bill costs $60, and this is paid in full. Her gas bill was $40, and she has already paid three-quarters of this. She makes another payment of $5 towards her gas bill while checking her budget. Her water bill is $40, which she has paid half of, and her internet bill is $25, which she has made 4 payments of $5 towards. Overall, how many dollars does Stephanie still need to pay to finish paying her bills?
A: Stephanie has paid three - quarters of her gas bill, which is 40 * 0.75 = $30. She then made another payment, which means she has paid 30 + 5 = $35 of her gas bill. She has paid half of her water bill, which is 40 * 0.5 = $20. She has made 4 payments towards her internet bill, which is a total of 4 * 5 = $20. Overall, her bills were 60 + 40 + 40 + 25 = $165. Overall, she has made payments of 60 + 35 + 20 + 20 = $135. Therefore, she still has to pay 165 – 135 = $30. The answer is 30.
Question: The rainy season is here, Jan collected 65 gallons of water in a barrel outside her home. She uses 7 gallons of water each to clean the two cars and uses 11 fewer gallons than the two cars to water the plants. Then, she uses half of the remaining gallons of water to wash the plates and clothes. How many gallons of water does Jan use to wash her plates and clothes?
Answer: She uses 7 x 2 = 14 gallons of water to clean the two cars. She uses 14 - 11 = 3 gallons of water to water the plants. The total gallons of water that she uses to clean the cars and to water the plants is 14 + 3 = 17. Jan has 65 - 17 = 48 gallons of water remaining after cleaning the cars and watering the plants. Jan uses 48 / 2 = 24 gallons of water to wash her plates and clothes. The answer is 24.
