[Question]James buys 3 dirt bikes for $150 each and 4 off-road vehicles for $300 each. It also cost him $25 to register each of these. How much did he pay for everything?
[Answer]The dirtbikes cost 3 * 150 = $450. The off - road vehicles cost 300 * 4 = $1200. He had to register 3 + 4 = 7 vehicles. That means registration cost 25 * 7 = $175. So the total cost of everything was 450 + 1200 + 175 = $1825. The answer is 1825.
Q: Frank has 7 one-dollar bills, 4 five-dollar bills, 2 ten-dollar bills, and 1 twenty-dollar bill. He goes to buy peanuts, which cost $3 a pound. He buys what he wants and has $4 in change. He plans to eat the peanuts all in one week. How many pounds does he eat on average per day?
A: Frank has $7 in one dollar bills because 7 x 1 = 7. Frank has $20 in five dollar bills because 4 x 5 = 20. Frank has $20 in ten dollar bills because 2 x 10 = 20. Frank has 67 dollars in total because 7 + 20 + 20 + 20 = 67. Frank spent $63 because 67 - 4 = 63. Frank bought 21 pounds of peanuts because 63 / 3 = 21. He eats 3 pounds a day on average because 21 / 7 = 3. The answer is 3.
Question: Mrs. Snyder used to spend 40% of her monthly income on rent and utilities. Her salary was recently increased by $600 so now her rent and utilities only amount to 25% of her monthly income. How much was her previous monthly income?
Answer: Let her previous monthly income be p. The cost of her rent and utilities was 40% of p which is (40 / 100) * p = 2p / 5. Her income was increased by $600 so it is now p + $600. The cost of her rent and utilities now amount to 25% of (p + $600) which is (25 / 100) * (p + $600) = (p + $600) / 4. Equating both expressions for cost of rent and utilities: 2p / 5 = (p + $600) / 4. Multiplying both sides of the equation by 20 gives 8p = 5p + $3000. Subtracting 5p from both sides gives: 3p = $3000. Dividing both sides by 3 gives p = $1000. The answer is 1000.
[Question]Axel bought an aquarium that was marked down 50% from an original price of $120. But he also paid additional sales tax equal to 5% of the reduced price. What was the total cost of the aquarium?
[Answer]The aquarium was bought for $120 x 50 / 100 = $60 less. So the marked down price of the aquarium was $120 - $60 = $60. Axel paid $60 x 5 / 100 = $3 additional for the sales tax. Therefore, the total cost of the aquarium was $60 + $3 = $63. The answer is 63.
[Question]There are two babysitters named Mila and Agnes. Mila makes $10 an hour while Agnes makes $15 an hour. Agnes works 8 hours each week. How many hours does Mila need to work to earn as much as Agnes in a month?
[Answer]
The weekly salary of Agnes is $15 x 8 = $120. So in a month, Agnes earns $120 x 4 = $480. Therefore, Mila needs to work for $480 / $10 = 48 hours to earn as much as Agnes's monthly earnings. The answer is 48.
