The sale price of an item is $545.00. If bought on sale for 25% off what was the original price of the item?\r
\n" ); document.write( "\n" ); document.write( "Let
\n" ); document.write( "Original price = x
\n" ); document.write( "25% of original price = x * 25% = x * 25/100 = x * 1/4 = x/4
\n" ); document.write( "Sale price = 545\r
\n" ); document.write( "\n" ); document.write( "Original price = Sale price + 25% of original price
\n" ); document.write( "x = 545 + x/4
\n" ); document.write( "Multiply by 4 both sides of the equation
\n" ); document.write( "4*x = 4*545 + 4*x/4
\n" ); document.write( "4x=2180+x
\n" ); document.write( "4x-x=2180
\n" ); document.write( "3x=2180
\n" ); document.write( "Divide by 3 both sides of above equation
\n" ); document.write( "3x/3=2180/3
\n" ); document.write( "x=726.66
\n" ); document.write( "Original price = x = 726.66
\n" ); document.write( "25% of original price = x * 25% = x * 25/100 = x * 1/4 = x/4 = 726.66/4 = 181.66
\n" ); document.write( "Sale price = 545\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
