Q: On Sunday Trey is going to do some chores at home. First, he wants to make a To Do list and count up how many things he has to do that day and how long it should take. He has several items under 'clean the house,' 'take a shower' and then 'make dinner.' In total there are 7 things to do to clean the house; 1 thing to do to take a shower; and 4 things to do to make dinner. If everything on Trey's list takes 10 minutes to do, how many hours total will it take to complete Trey's list?
A: On Trey's list there are 7 + 1 + 4 things to do = 12 things to do in total. Each thing takes 10 minutes to do, so 10 minutes x 12 things = 120 minutes. An hour has 60 minutes in it, so 120 minutes / 60 minutes in an hour = 2 total hours it will take Trey to complete his list. The answer is 2.
Question: James paves a new parking lot. It is 400 feet by 500 feet. Only 80% of that is useable for parking. It takes 10 square feet to park a car. How many cars can be parked?
Answer: The parking lot is 400 * 500 = 200,000. There are 200,000 * .8 = 160,000 square feet of parking space. That means he can park 16,0000 / 10 = 16000 cars. The answer is 16000.
[Question]James is a first-year student at a University in Chicago. He has a budget of $1000 per semester. He spends 30% of his money on food, 15% on accommodation, 25% on entertainment, and the rest on coursework materials. How much money does he spend on coursework materials?
[Answer]Accommodation is 15% * $1000 = $150. Food is     30% * $1000 = $300. Entertainment is  25% * $1000 = $250. Coursework materials are thus $1000 - ($150 + $300 + $250) = $300. The answer is 300.
Q: Ten boys brought 15 popsicle sticks each. Twelve girls brought 12 popsicle sticks each. How many fewer popsicle sticks did the girls bring than the boys?
A: The boys brought a total of 10 x 15 = 150 popsicle sticks. The girls brought a total of 12 x 12 = 144 popsicle sticks. Therefore, the girls brought 150 - 144 = 6 fewer popsicle sticks than the boys. The answer is 6.
Question: Ann, Becky, and Julia are working at a pharmacy, every day for 8 hours. Each of them is providing service to 7 customers per hour. One day Julia had to finish her work earlier, so she was working only for 6 hours. How many customers did all three of these women serve that day in total?
Answer: Ann and Becky have worked for 8 hours each, so both of them worked for 2 people * 8 hours / person = 16 hours. All three of them, including Julia, were working for 16 hours + 6 hours = 22 hours. So in total, they all have served 7 customers / hour * 22 hours = 154 customers in one day. The answer is 154.
