A pair of shoes goes on sale for 15 %15% off and then on the clearance rack for an additional 25 %25% off. A customer walks in with a 5 %5% off coupon good on all clearance items and buys the shoes.

Let $\"+C+\"$ = the original cost of the shoes
\n" ); document.write( "The markup seems to be $\"+C+%2B+1.3C+=+2.3C+\"$
\n" ); document.write( "That's 130% OVER cost
\n" ); document.write( "-------------
\n" ); document.write( "After 15% off sale, the price of the shoes is:
\n" ); document.write( " $\"+2.3C+-+.15%2A%28+2.3C+%29+\"$
\n" ); document.write( " $\"+.85%2A2.3C+=+1.955C+\"$
\n" ); document.write( "-----------------------
\n" ); document.write( "After 25% more off, the price of shoes is:
\n" ); document.write( " $\"+1.955C+-+.25%2A%28+1.955C+%29+\"$
\n" ); document.write( " $\"+.75%2A1.955C+=+1.46625C+\"$
\n" ); document.write( "----------------------
\n" ); document.write( "With 5% off coupon, the price is:
\n" ); document.write( " $\"+1.46625C+-+.05%2A1.46625C+\"$
\n" ); document.write( " $\"+.95%2A1.46625C+=+1.3929375C+\"$
\n" ); document.write( "-----------------------------
\n" ); document.write( "The store's profit as % of cost is:
\n" ); document.write( " $\"+%28+1.3929375C+-+C+%29%2A100+\"$
\n" ); document.write( " $\"+.3929375%2A100+\"$
\n" ); document.write( " $\"+39.29+\"$
\n" ); document.write( "The profit is 39.29% of original cost
\n" ); document.write( "--------------------------------
\n" ); document.write( "Strange numbers. Check my math. \n" ); document.write( "
