A new apartment complex purchased 60 toilets and 20 shower heads. If the price of a toilet is three times the price of a shower head, what percent of the total cost was the cost of all the shower heads?
Options: A) 13 B) 297 C) 26 D) 19 E) 10
Explanation:   Let the cost of shower head is x. Then the cost of the toilet = 3x.   Total cost of 60 toilets and 20 shower heads = 60 × 3x + 20 × x = 200x   So shower heads cost as a percentage of total cost = 20x20x20x20x × 100 = 10%   Answer:10
