Answer this question:Amber goes to the store and buys 10 rolls of toilet paper, 7 rolls of paper towels, and 3 boxes of tissues. One roll of toilet paper costs $1.50. One roll of paper towels costs $2. If the total cost of all the items is $35, how much does one box of tissues cost?
The total cost of toilet paper is 10 * $1.5 = $15. The total cost of paper towels is 7 * $2 = $14. The total cost of tissues is $35 - $15 - $14 = $6. The cost of one box of tissues is $6 / 3 = $2.
The answer is 2.

Answer this question:One kilogram of tomatoes is 20% cheaper than one kilogram of cucumbers. One kilogram of cucumbers costs $5. What is the price of two kilograms of tomatoes and three kilograms of cucumbers?
One kilogram of tomatoes is 20 / 100 * 5 = $1 cheaper than one kilogram of cucumbers. This means that one kilogram of tomatoes costs 5 - 1 = $4. So two kilograms of tomatoes is a cost of 2 * 4 = $8. And three kilograms of cucumbers is a cost of 3 * 5 = $15. So the price for both products would be 8 + 15 = $23.
The answer is 23.

Answer this 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?
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.

Answer this question:Luther designs clothes for a high fashion company. His latest line of clothing uses both silk and cashmere fabrics. There are ten pieces made with silk and half that number made with cashmere. If his latest line has thirteen pieces, how many pieces use a blend of cashmere and silk?
Luther has 10 / 2 = 5 pieces made with cashmere. He has 13 - 10 = 3 pieces made without silk using only cashmere. Thus, Luther has 5 - 3 = 2 pieces made using a blend of cashmere and silk.
The answer is 2.
