Question: Cordelia is dyeing her hair red. To get the color she wants, she first has to bleach her dark brown hair to blonde, and then she has to apply the dye. The whole process will take 9 hours. Dyeing takes twice as long as bleaching. How many hours will it take Cordelia to bleach her hair?
Answer: Let H be the number of hours it takes Cordelia to bleach her hair. A dye treatment takes twice as long, so it takes 2H. Thus, bleaching and dying will take H + 2H = 3H = 9 hours. Therefore, it will take Cordelia H = 9 / 3 = 3 hours to bleach her hair. The answer is 3.
[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: Teairra has 5 shirts and 24 pairs of pants in her closet. If 3 of Teairra's shirts are plaid and 5 of Teairra's pants are purple, how many shirts and pants does Teairra has which are neither plaid nor purple?
A: If 3 of Teairra's shirts are plaid, 5 - 3 = 2 shirts are not plaid. Also, 5 of Teairra's pants are purple, meaning 24 - 5 = 19 pants are not purple. The number of shirts and pants that Teairra has which are neither plaid nor purple is 19 + 2 = 21. The answer is 21.

Pauline planted in total 3 * 5 = 15 tomatoes. Pauline also planted 5 * 4 = 20 cucumbers. In total Pauline planted 15 + 20 + 30 = 65 different vegetables. The whole garden can be filled up with 10 * 15 = 150 different vegetables. So Pauline could plant 150 - 65 = 85 more vegetables in her garden. The answer is 85.
