Question: If Pete read twice as many books as Matt did last year, and this year he doubles that number while Matt reads only 50% more, how many books does Pete read across both years if Matt read 75 books in his second year?
Answer: First, we need to find the amount Matt read both years to establish what Pete read, so to find Matt's first - year total we multiply 75 / 1.5 = 50 books the previous year. Since Pete read twice as many books as Matt did in the first year, and Matt's first - year total is 50, this means Pete read 50 * 2 = 100 books his first year. Since Pete doubled the number of books he read the following year, this means Pete read 100 * 2 = 200 books the following year. We add the two years of Pete's reading together to find 200 + 100 = 300 books read in total. The answer is 300.
[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.
Q: Tim spent $50.00 on Chinese take-out. 80% of the cost went to 4 entrees. The rest of the money went to 2 appetizers that each cost the same amount. How much was the price of a single appetizer?
A: He spent $50.00 and 80% of the meal went to entrees so he spent 50 * .80 = $40.00 on entrees. He spent $50.00 and $40.00 went to entrees so that leaves $50 - $40 = $10.00 for appetizers. Each appetizer costs the same amount and he spent $10.00 all together so each appetizer is $10 / 2 = $5.00. The answer is 5.
Question: Vicente bought 5 kilograms of rice and 3 pounds of meat. Each kilogram of rice is $2 and a pound of meat is $5. How much did Vicente spend in total?
