Math CentralQuandaries & Queries


Question from Willa, a student:

So, I have this question from my summer packet: "Gwen buys 3 identical pairs of shoes at store a. She pays $110.25 after the discount what is the regular price of each pair? ( 40% off)"

Hi Willa,

Suppose that the before sale price of each pair of shoes is $P$ dollars. What she actually paid for each pair of shoes was $\large \frac{110.25}{3}$ dollars. There was a discount of $40\%$ of the price $P$ dollars and hence she paid $60\%$ of $P$ dollars for each pair. Hence

\[0.60 \times P = \frac{110.25}{3}\]

Solve for $P.$
