a tv set is marked down $72, to be placed on sale. If this is a 4% decrease from the original price, what was the selling price before the sale?
\n" ); document.write( "---------------
\n" ); document.write( "If you mean marked down to $72:
\n" ); document.write( "$72 is 96% of the OP (original price) (100% - 4%)
\n" ); document.write( "96% = 0.96
\n" ); document.write( "OP*0.96 = 72
\n" ); document.write( "OP = 72/0.96 = $75
\n" ); document.write( "-----------------
\n" ); document.write( "If you mean the reduction of 4% is a reduction of $72:
\n" ); document.write( "4% = $72
\n" ); document.write( "1% = $18
\n" ); document.write( "100% = $1800
\n" ); document.write( "
