A music store marks up the instruments it sells by 30%. If the store bought a guitar for $45, what will be its store price? Round your answer to the nearest hundredth (second) decimal place.

= 58.50

Step-by-step explanation:

We need to determine the markup

markup = original price * markup percent

markup = 45 * 30%

markup = 45*.3

=13.5

Add the markup to the original price

New price = 45+13.5

= 58.5
