Question: Linda is painting her bedroom. Her bedroom has 4 walls, with the room being 20 feet wide by 20 feet long by 8 feet tall. One wall has a 3-foot by 7-foot doorway. A second wall has a 6-foot by 4-foot window. A third wall has a 5-foot by 7-foot doorway to a walk-in-closet. And the fourth wall is completely solid. What is the total area of wall space that Linda will have to paint?
Answer: The solid wall is 8 ft. * 20 ft. = 160 sq. ft. The doorway is 3 ft. * 7 ft. = 21 sq. ft. The window is 6 ft. * 4 ft. = 24 sq. ft. The closet door is 5 ft. * 7 ft. = 35 sq. ft. The total area of the doors and windows is 21 sq. ft + 24 sq. ft. + 35 sq. ft. = 80 sq. ft. The solid wall is 160 sq. ft., so before the areas of the doors and window are taken into account, the total wall area is 4 * 160 sq. ft. = 640 sq. ft. Taking into account the doors and window, the total wall area Linda will have to paint is 640 sq. ft. - 80 sq. ft. = 560 sq. ft. The answer is 560.
[Question]A global gym decides to replace all of its cardio machines. They have 20 gyms. Each gym has 10 bikes, 5 treadmills, and 5 elliptical machines. The bikes cost $700 each. The treadmills cost 50% more than that. The elliptical machines are twice as expensive as the treadmills. How much does it cost to replace everything?
[Answer]The gym needs to buy 20 * 10 = 200 bikes. 20 * 5 = 100 each of treadmills and ellipticals. So the bikes cost 200 * 700 = $140,000. The treadmills cost 700 * 1.5 = $1,050 each. So they cost a total of 1050 * 100 = $105,000. The ellipticals each cost 1050 * 2 = $2100. So in total the ellipticals cost 2100 * 100 = $210,000. So the total cost of everything is 140,000 + 105,000 + 210,000 = $455,000. The answer is 455000.
Q: Jenny makes and freezes pans of lasagna all week so she can sell them at the market on the weekend. It costs Jenny $10.00 in ingredients to make 1 pan of lasagna. If she makes and sells 20 pans over the weekend at $25.00 apiece, how much does she make after factoring in expenses?
A: Each pan costs $10.00 to make so for 20 pans, it will cost 10 * 20 = $200.00. She sells each of the 20 pans for $25.00 each so she will make 20 * 25 = $500.00. She makes $500.00 and spent $200.00 on ingredients so she makes 500 - 200 = $300.00. The answer is 300.
Question: James buys 10 shirts and half as many pants. The shirts cost $6 each and the pants cost $8 each. How much did everything cost?
Answer: He bought 10 / 2 = 5 pants. The shirts cost a total of 10 * 6 = $60. The pants cost 8 * 5 = $40. So the total cost was 60 + 40 = $100. The answer is 100.
[Question]Amanda charges $20.00 per hour to help clean out and organize a person's home. She has 5 1.5 hours appointments on Monday, a 3-hours appointment on Tuesday and 2 2-hours appointments on Thursday. On Saturday, she will spend 6 hours at one client's house. How much money will she make this week?
[Answer]She has 5 1.5 hour appointments on Monday for a total of 5 * 1.5 = 7.5 hours. She has 2 2 hour appointments on Thursday for a total of 2 * 2 = 4 hours. She is working 7.5 hours on Monday, 3 hours on Tuesday, 4 hours on Thursday and 6 hours on Saturday for a total of 7.5 + 3 + 4 + 6 = 20.5 hours. She charges $20.00 an hour and is working 20.5 hours a week for a total of 20 * 20.5 = $410.00. The answer is 410.
[Question]A library has a collection of 100 historical novels arranged on a shelf. 5 people borrow 2 books each from the shelf on a particular day, and 20 more books are borrowed from the shelf on the second day. How many books are remaining on the shelf after the second day?
[Answer]
Five people borrowed 5 people * 2 books / person = 10 books on the first day. After the second day, the total number of borrowed books increased to 10 books + 20 books = 30 books. The total number of books on the shelf after the second day is 100 books - 30 books = 70 books. The answer is 70.
