Answer the following 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?
Step-by-step reasoning process: 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.
The answer is 1680000.

Answer the following question.
Elijah is painting his living room and decides to buy masking tape to make his painting neater. 2 of his walls are 4 meters wide and the other 2 walls are 6 meters wide. Elijah needs enough masking tape to cover the entire width of each wall and can order the exact amount of masking tape he needs. How many meters of masking tape does Elijah need to order?
Step-by-step reasoning process: For 2 of the walls, Elijah will need 2 walls * 6 meters each = 12 meters of masking tape. For the other 2 walls, he will need 2 walls * 4 meters each = 8 meters of masking tape. He will therefore need a total of 12 + 8 = 20 meters of masking tape.
The answer is 20.

Answer the following question.
If you buy a dozen of doughnuts, it costs $8; but if you buy 2 dozens, it costs $14. How much will you save from buying 3 sets of 2 dozens than buying 6 sets of 1 dozen?
Step-by-step reasoning process: Six sets of 1 dozen of doughnuts cost $8 x 6 = $48. Three sets of 2 dozens of doughnuts cost $14 x 3 = $42. Therefore, you can save $48 - $42 = $6.

Answer the following question.
A watermelon stand sold 46 watermelons. Seventeen customers bought one melon, three customers bought three melons, and the rest bought two melons. How many customers bought two watermelons?
Step-by-step reasoning process: The customers that bought one watermelon bought 1 * 17 = 17 melons. The customers that bought three melons bought 3 * 3 = 9 melons. The stand sold 46 - 17 - 9 = 20 melons to customers who bought 2 melons. Thus, 20 / 2 = 10 customers bought two watermelons.
The answer is 10.
