9) 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?

1. 9%
2. 10%
3. 11%
4. 13%
5. 15%

To solve this, you can place values for the toilets and shower heads. If you apply $3 for each toilet and $1 for each shower head, your total cost will be $200. Of this, $20 or 10% is spent on shower heads.
