Answer this question:Jackson works 5 days a week going door-to-door collecting for charity. His goal is to raise $1000 for the week. He earned $300 on Monday and $40 on Tuesday. If he collects an average of $10 for every 4 houses he visits, how many houses will he have to visit on each of the remaining days of the week to meet his goal?
First find the total amount Jackson still needs to collect: $1000 - $300 - $40 = $660. Then subtract the number of days he already worked from the number of workdays in the week to find how many more days he'll work: 5 days - 2 days = 3 days. Then divide the total amount he still needs to earn by the number of days he has to earn it to find how much he needs to earn per day: $660 / 3 days = $220 / day. Then find how much money he collects per house: $10 / 4 houses = $2.50 / house. Then divide the amount he needs to collect per day by the amount he collects per house to find how many houses he needs to visit per day: $220 / day / $2.50 / house = 88 houses / day.
The answer is 88.

Answer this question:Jennie drives to her son's house in 5 hours when there is heavy traffic. When there is no traffic the same trip takes only 4 hours. If her son's house is 200 miles away, what is the difference between her average speed when there is heavy traffic and when there is no traffic?
Jennie can cover the 200 - mile distance in 5 hours when there is heavy traffic, so her average speed is 200 / 5 = 40mph. She can cover the same distance in 4 hours when there is no traffic for an average speed of 200 / 4 = 50mph. The difference in average speed between the two scenarios is (50 - 40)mph = 10mph.
The answer is 10.

Answer this question:Mrs. Oaklyn buys handmade rugs at $40 each and sells them at $60 each. If she bought 20 rugs, calculate the profit she will make from selling the rugs.
Since she buys one rug at $40 and sells it at $60, she makes a profit of $60 - $40 = $20. If she bought 20 rugs at $40 and sold them at $60 each, she made a profit of 20 * $20 = $400.
The answer is 400.

Answer this question:There were 180 apples in each crate. 12 such crates of apples were delivered to a factory. 160 apples were rotten and had to be thrown away. The remaining apples were packed into boxes of 20 apples each. How many boxes of apples were there?
The total number of apples delivered was: 180 apples x 12 crates = 2160 apples. So, the number of remaining apples after throwing away the rotten ones was: 2160 apples 160 apples = 2000 apples. And now, we can find the total number of boxes of apples by dividing the remaining number of apples by the number of apples per box: 2000 apples / 20 apples / box = 100 boxes of apples.
The answer is 100.
