[Question]Brandon has been fired from half the businesses in town and has quit from a third of them. If there are 72 business in town, how many businesses can he still apply to?
[Answer]First divide the total number of businesses by 2 to find how many businesses Brandon hasn't been fired from: 72 businesses / 2 = 36 businesses. Then divide the total number of businesses by 3 to find how many businesses Brandon quit from: 72 businesses / 3 = 24 businesses. Then subtract that number from the number of businesses he hasn't been fired from to find the number of businesses where he can still apply: 36 businesses - 24 businesses = 12 businesses. The answer is 12.

[Question]Trevor and two of his neighborhood friends go to the toy shop every year to buy toys. Trevor always spends $20 more than his friend Reed on toys, and Reed spends 2 times as much money as their friend Quinn on the toys. If Trevor spends $80 every year to buy his toys, calculate how much money in total the three spend in 4 years.
[Answer]
If Trevor spends $20 more than Reed every year to buy toys, Reed spends $80 - $20 = $60. Since Reed uses $60 every year to buy toys, his friend Quinn uses 60 / 2 = $30 every year to buy toys. The total amount of money the three spend in a year together to buy toys is $30 + $60 + $80 = $170. The total amount of money the three will use to buy toys in 4 years is $170 * 4 = $680. The answer is 680.
