Problema Solution
A retailer has some skirts that cost $21 each. She wants to sell them at a profit of 30% of the selling price. What price should she charge for the skirts?
Answer provided by our tutors
we assume "at a profit of 30% of the selling price" means "at a profit of 30% over the cost of the skirts"
we add 30% of $21:
21 + 0.30*21 = 27.3
she should charge $27.30 for the skirts
