Algebra.Com's Answer #91634 by checkley71(8403) ![]() You can put this solution on YOUR website! If you want to find a reduction of 20% and you don't have the original number, then you need to assign the original price an unknown(x)and subtract 20% from x. \n" ); document.write( "Thus we have the following equation. \n" ); document.write( "-------------------------------------------------------------------- \n" ); document.write( "(X-.2X)=12,590 SALE PRICE MINUS 20% OF THIS PRICE EQUALS $12,590. \n" ); document.write( ".8X=12,590 \n" ); document.write( "X=12,590/.8 \n" ); document.write( "X=$15,737.50 WAS THE ORIGINAL PRICE. \n" ); document.write( " |
