A refrigerator was on sale for 20% off. Marcus received an additional 30% of any current price in the store. If he uses the coupon to buy the refrigerator, the price would be $487.20 before taxes. What was the original price?
\n" ); document.write( "----
\n" ); document.write( "Let original price be \"x\":
\n" ); document.write( "----
\n" ); document.write( "Equation:
\n" ); document.write( "20% off means the price was 0.8x
\n" ); document.write( "additional 30% off means the price was 0.7*0.8x\r
\n" ); document.write( "\n" ); document.write( "------
\n" ); document.write( "Solve for \"x\":
\n" ); document.write( "0.7*0.8x = 487.20
\n" ); document.write( "x = $870 (original price)
