You can put this solution on YOUR website! 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?
----
Let original price be "x":
----
Equation:
20% off means the price was 0.8x
additional 30% off means the price was 0.7*0.8x
------
Solve for "x":
0.7*0.8x = 487.20
x = $870 (original price)
