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 with step-by-step thinking: 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.
So the answer is 160.

Question: A company has 500 employees, each paid $12 per hour, working 10 hours a day, five days a week, 4 weeks a month. In August, the amount of work increased, and the company hired 200 more people. How much money does the company pay in total per month after the new hires?
Answer with step-by-step thinking:
The total pay per employee in a day is 12 * 10 = $120. An employee works for 5 * 4 = 20 days in a month. The total amount of money paid to each employee monthly is 20 * 120 = $2400. When the number of employees increased to 500 + 200 = 700 after the new hires in August. The company pays a total of 700 * 2400 = $1680000 per month to its employees.
So the answer is 1680000.
