[Question]: As a freelancer, Katherine takes 20 hours to develop a website for her clients. Her junior, Naomi, takes 1/4 times more time to complete creating a similar website. If many clients required her to build their websites in a particular year, and she gave her junior 30 websites to develop, calculate the total number of hours Katherine's junior took to create the 30 websites.
[Answer]: Katherine's junior takes 1 / 4 * 20 = 5 more hours to build a similar website as Katherine. The total number of hours Katherine's junior takes to build a website is 20 + 5 = 25 hours. If Katherine gave her junior 30 websites to build, her junior spent 30 * 25 = 750 hours on building the 30 websites.
So the answer is 750.

[Question]: The sewers in Middleton can handle 240,000 gallons of run-off. Each hour of rain produces 1000 gallons of runoff. How many days of rain can the sewers handle before they overflow?
[Answer]: First find how many hours of runoff the sewers can handle: 240,000 / 1000 gallons / hour = 240 hours. Then divide that time by the number of hours per day to find how many days of rain the sewers can handle: 240 hours / 24 hours / day = 10 days.
So the answer is 10.

[Question]: Jason is trying to figure out whether he can afford a new car. The car he wants costs $32,000, and he can make a down payment of $8,000. He'll have to get a loan for the rest of the amount and make 48 equal monthly payments on it. Each month, he also has to pay interest equal to 5% of that month's payment. How much will Jason's monthly payments be?
[Answer]:
First figure out how much the loan will be: $32,000 - $8,000 = $24,000. Then divide the loan amount by the number of payments to find the monthly payment before interest: $24,000 / 48 months = $500 / month. Then multiply the loan amount by 5% to find out how much the interest is: $500 / month * .05 = $25 / month. Then add the interest to the payment amount to find the total monthly payment: $500 / month + $25 / month = $525 / month.
So the answer is 525.
