Q: Ms. Estrella is an entrepreneur with a startup company having 10 employees. The company makes a revenue of $400000 a month, paying 10% in taxes, 5% of the remaining amount on marketing and ads, 20% of the remaining amount on operational costs, and 15% of the remaining amount on employee wages. Assuming each employee receives the same wage, calculate the amount of money each employee is paid monthly.
A: The company pays a total of 10 / 100 * $400000 = $40000 on taxes. After taxes, the company revenue is $400000 - $40000 = $360,000. The costs of marketing and ads campaign are 5 / 100 * $360000 = $18000. After deducting the costs of marketing and adds campaign, the company remains with = $342,000 in revenue. Operational costs for the company are 20 / 100 * $342000 = $68400. After taking out the operational costs, the company remains with $342000 - $68400 = $273600. The company also pays employee wages of 15 / 100 * $273600 = $41040. If the total number of employees is 10, each employee is paid a salary of $41040 / 10 = $4104 per month. The answer is 4104.

Q: John is a hack author. He writes a book every 2 months. He has been writing for 20 years and has earned an average of $30,000 per book. How much money has he made writing?
A: He writes 12 / 2 = 6 books a year. That means he has written 6 * 20 = 120 books. So he has made 120 * 30,000 = $3,600,000 from writing. The answer is 3600000.

Q: Marcy is the lunch monitor in an elementary school cafeteria. She gives 5 time-outs for running, 1 less than five times that number of time-outs for throwing food, and 1/3 the number of food-throwing time-outs for swearing. If each time-out is 5 minutes, how much time do the students spend in time-out total?
A:
First multiply the number of running time - outs by 5: 5 time - outs * 5 = 25 time - outs. Then subtract 1 from that number to find the number of food - throwing time - outs: 25 time - outs - 1 = 24 time - outs. Then divide that number by 3 to find the number of swearing time - outs: 24 time - outs / 3 = 8 time - outs. Then add the number of each kind of time - out to find the total number: 8 time - outs + 24 time - outs + 5 time - outs = 37 time - outs. Then multiply that number by the length of each time - out to find the total time the students spend in time - out: 37 time - outs * 5 minutes / time - out = 185 minutes. The answer is 185.
