A retailer has some skirts that cost her $24. If she sells them for $31.50, find ther rate of profit based on the cost.

what is asked in the problem?

    Find the rate of the profit based in the cost.

Given:
    A retailer has skirt that cost her $24
    She sells them for $31.50

Solution:
Let us find the profit after she sells a skirt
            $31.50 - 24 = $ 7.50

Then we are going to find how many percent is $7.50 based on the cost ($24)

     $7.50 is what percent of $24
      7.50 = x * 24
      7.50 = 24x
    0.3150 = x
      31.5% = x
