[Question]There are 7 trucks that have 20 boxes. There are 5 trucks that have 12 boxes. Each box holds 8 containers of oil. If all of the oil is evenly redistributed onto 10 trucks, how many containers of oil will each truck have?
[Answer]Boxes of oil = 7 * 20 + 5 * 12 = 200 boxes. Containers of oil = 200 boxes * 8 containers = 1600 containers of oil. 1600 / 10 = 160. Each truck will carry 160 containers of oil. The answer is 160.

[Question]Donna worked 2 hours every morning walking dogs in her neighborhood for $10.00 an hour. 5 days a week, after school, she worked at a card shop for 2 hours and made $12.50 an hour. On the weekends, she usually made $10.00 an hour babysitting and was guaranteed 4 hours every Saturday from her neighbor. How much money did she make over 7 days?
[Answer]She makes $10.00 an hour for 2 hours walking dogs so she makes 10 * 2 = $20.00 every morning. Over 7 days she makes 7 * 20 = $140.00 a week. She makes $12.50 for 2 hours working at a card shop so she makes 12.5 * 2 = $25.00. She works there 5 days a week so she makes 5 * 25 = $125.00 a week. She also babysits for 4 hours making $10.00 an hour for a total of 4 * 10 = $40.00. Over 7 days, she makes 140 + 125 + 40 = $305.00. The answer is 305.
