[Question]John decides to start collecting art. He pays the same price for his first 3 pieces of art and the total price came to $45,000. The next piece of art was 50% more expensive than those. How much did all the art cost?
[Answer]The first 3 pieces each cost 45000 / 3 = $15,000. So the next piece was 15,000 * .5 = $7,500 more expensive. That means it cost 15,000 + 7,500 = $22,500. That means in total he spent 45,000 + 22,500 = $67,500. The answer is 67500.
Q: Janet is trying to decide whether to quit her job and start freelancing. She works 40 hours a week at both jobs. She get paid $30/hour at her current job, and would get paid $40/hour as a freelancer. However, she'd have to pay an extra $25 a week in FICA taxes plus $400/month in healthcare premiums. How much more would Janet make per month as a freelancer if there are four weeks in a month?
A: First find the difference in hourly wages: $40 / hour - $30 / hour = $10 / hour. Then multiply that difference by the number of hours she works in a week to find the weekly difference: $10 / hour * 40 hours / week = $400 / week. Then multiply that amount by the number of weeks in a month to find the monthly difference in her earnings: $400 / week * 4 weeks / month = $1600 / month. Then find the total additional amount Janet pays in FICA taxes: $25 / week * 4 weeks / month = $100 / month. Then subtract Janet's extra FICA taxes and healthcare premium from the additional money she earns to find the net increase in her pay from freelancing: $1600 / month - $400 / month - $100 / month = $1100 / month. The answer is 1100.

[Question]Five hundred people attended the band concert. For that concert, the band gets 70% of the ticket price. If each ticket costs $30 and there are 4 members of the band, how much did each band member get from that concert?
[Answer]The total earnings from the ticket are $30 x 500 = $15000. The band got $15000 x 70 / 100 = $10500. So each band member got $10500 / 4 = $2625. The answer is 2625.
[Question]Tom decides to lease a car. He drives 50 miles on Monday, Wednesday, and Friday, and Sunday for the rest of the days he drives 100 miles. He has to pay $.1 per mile he drives. He also has to pay a weekly fee of $100. How much does he have to pay in a year.
[Answer]
He does the long drive 7 - 4 = 3 days a week. So he drives a total of 4 * 50 + 3 * 100 = 500 miles a week. That means the car cost 500 * .1 = $50 just for the mileage per week. So he pays 100 + 50 = $150 per week for the car. That means the total cost of the car is 150 * 52 = $7800 a year. The answer is 7800.
