Set x = the original price of the calculator
\n" ); document.write( "(x-0.10x)+ 0.05*(x-0.10x)
\n" ); document.write( "In the above, (x-0.10x) represents the original price - 10% of the original price.
\n" ); document.write( "(x-0.10x)*0.05 represents 5% times original price - 10%
\n" ); document.write( "******************
\n" ); document.write( "(x-0.10x)+ 0.05*(x-0.10x)
\n" ); document.write( "(0.9x) + 0.05(0.9x)
\n" ); document.write( "(0.9x) + (0.045x)
\n" ); document.write( "(0.9+0.045)x
\n" ); document.write( "(0.945)x
\n" ); document.write( "So (0.945)x = 945
\n" ); document.write( "divide each side by 0.945
\n" ); document.write( " x = 945/0.945
\n" ); document.write( " x = 1000
\n" ); document.write( "
\n" );
