Question

A sign says that the price marked on all music equipment is 30% off the original price. You buy an electric guitar for the sale price of $315.

What is the original price?

Answer 1

The original price is $409.5

Explanation:

the 2 numbers that you have in this equation are 315 and 30% (or .30)

You want to multiply 315 by .3 to get an answer of 94.5

That's the amount of money that was marked down on the guitar

So you want to add 94.5 to 315 which gives you 409.5

so $409.5 is your answer
