[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]: 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.

[Question]: Jim has a pail with rocks in it. The average weight of a rock is 1.5 pounds. A local rock collector agrees to pay him $4 for every pound of rocks. If he makes $60 off the sale, how many rocks were in the bucket?
[Answer]: There were 15 pounds of rocks in the bucket because 60 / 4 = 15. There were 10 rocks in the bucket because 15 / 1.5 = 10.
So the answer is 10.

[Question]: Janet is trying to decide whether to quit her job and start freelancing. She works 40 hours a week at both jobs. She get paid $30/hour at her current job, and would get paid $40/hour as a freelancer. However, she'd have to pay an extra $25 a week in FICA taxes plus $400/month in healthcare premiums. How much more would Janet make per month as a freelancer if there are four weeks in a month?
[Answer]:
First find the difference in hourly wages: $40 / hour - $30 / hour = $10 / hour. Then multiply that difference by the number of hours she works in a week to find the weekly difference: $10 / hour * 40 hours / week = $400 / week. Then multiply that amount by the number of weeks in a month to find the monthly difference in her earnings: $400 / week * 4 weeks / month = $1600 / month. Then find the total additional amount Janet pays in FICA taxes: $25 / week * 4 weeks / month = $100 / month. Then subtract Janet's extra FICA taxes and healthcare premium from the additional money she earns to find the net increase in her pay from freelancing: $1600 / month - $400 / month - $100 / month = $1100 / month.
So the answer is 1100.
