Q: Jackson wants to go on a shopping spree, so his mom says she will give him some spending money if he does extra chores. She promises $5 per hour spent on chores. Jackson spends 2 hours vacuuming, and decides to do this twice. He also spends 0.5 hours washing dishes, and three times as long cleaning the bathroom. How much spending money has Jackson earned?
A: Jackson spent a total of 2 * 2 = 4 hours vacuuming. This means he earned 4 * $5 = 20 dollars from vacuuming. He earned 0.5 * $5 = 2.5 dollars from washing dishes. Cleaning the bathroom took three times as long as the dishes, so he spent 0.5 * 3 = 1.5 hours in the bathroom. This means he earned 1.5 * $5 = $7.5 from cleaning the bathroom. In total, he has earned $20 + $2.5 + $7.5 = $30. The answer is 30.
Question: Nancy's ex owes her child support. He's supposed to pay 30% of his income each year. For 3 years, he made $30,000/year, then he got a 20% raise for the next four years. If he's only ever paid $1,200, how much does he owe her?
Answer: First find how much money the ex made during the first 3 years by multiplying his annual earnings by the number of years: 3 years * $30,000 / year = $90,000 / . Then find how much his raise was by multiplying his salary by the percentage raise: $30,000 / year * 20% = $6,000 / year. Then add the raise to his original salary to find his new salary: $6,000 / year + $30,000 / year = $36,000 / year. Then find how much he made working at the new salary by multiplying it by the 4 years he worked: 4 years * $36,000 / year = $144,000. Add his earnings from the three years and the four years to find his total earnings: $144,000 + $90,000 = $234,000. Now multiply his total earnings by 30% to find how much he was supposed to pay: $234,000 * 30% = $70,200. Now subtract the amount he paid from this number to find how much he owes: $70,200 - $1,200 = $69,000. The answer is 69000.
