A 20% discount means that the original price has been reduced by 20%.
\n" ); document.write( "To find the original price if the sales price of $36.00 includes a 20% discount, let x = the original price. The sales price is x - 20% of x and this equals $36.00. The algebra looks like this, after changing the 20% to its decimal equivalent of 0.2:
\n" ); document.write( " $\"x+-+0.2x+=+36\"$ Simplify and solve for x.
\n" ); document.write( " $\"0.8x+=+36\"$ Divide both sides by 0.8
\n" ); document.write( " $\"x+=+45\"$
\n" ); document.write( "The original price was $45.00\r
\n" ); document.write( "\n" ); document.write( "Check:
\n" ); document.write( " $\"45+-+0.2%2845%29+=+45+-+9\"$ = 36 \n" ); document.write( "
