There are many ways to solve this problem. One way to solve it is using proportions:\r
\n" ); document.write( "\n" ); document.write( "1. Set up proportions:\r
\n" ); document.write( "\n" ); document.write( " $\"%2832.30%2Fx%29=%280.85%2F1.00%29\"$ \r
\n" ); document.write( "\n" ); document.write( "This is because the item is 85% of it's original price, and we want to find the full price.\r
\n" ); document.write( "\n" ); document.write( "2. Cross multiply:\r
\n" ); document.write( "\n" ); document.write( " $\"%2832.30%29%2A%281.00%29=%280.85%29%2A%28x%29\"$ \r
\n" ); document.write( "\n" ); document.write( "3. Simplify:\r
\n" ); document.write( "\n" ); document.write( " $\"32.30=0.85x\"$ \r
\n" ); document.write( "\n" ); document.write( "4. Divide by 0.85 to get:\r
\n" ); document.write( "\n" ); document.write( "[$38.00=x]\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
