Question

Joanna plans to sell her saxophone on commission. The music store takes 30% of the selling

price, and Joanna wants to make $400 on the sale. What should she set as the selling price?

Answer 1

If the music store takes 30%, then Joanna keeps 70%.

Also, Joanna want to keep $400 from the sale.

So, we need to figure out "400 is 70% of what number?"

We need to solve 400 = 0.7x.

(divide both sides by 0.7)

This gives us x = 571.43 (rounded to the penny).
