Question 1076389
A shoe store marks up the price of its shoes at 140% over cost. A pair of shoes goes on sale for 15% off and then on the clearance rack for an additional 25 % off. A customer walks in with a 10% off coupon good on all clearance items and buys the shoes. Express the​ store's profits on these shoes as a percentage of the original cost.

The​ store's profit as a percentage of the cost of the original shoe is WHAT PERCENT?


thank you. sorry the other one I submitted was doing the percentages twice.
<pre>Let cost be C
Then markup price = 2.4C
Selling price: [.85(.75)(.9) * 2.4C] = 1.377C. 
Therefore, {{{highlight_green(matrix(1,6, Profit, "%", "=",  (1 - 1.377) * 100, "=", 37.7))}}}
