Answer:
Original price = $820
Explanation:
We know that the product of the discount percentage and the original price subtracted from the original price = the new price as
O - (15% * O) = N, where
- O is the original price
- 0.15 is 15% as a decimal,
- and N is the new price.
Thus, if we allow O to represent the original price and plug in 697 for N, we can find O, the original price:
O - (0.15O) = N
O - (0.15O) = 697
O - 0.15O = 697
0.85O = 697
O = 820
Checking our answer:
We can check our answer by making sure that 15% (aka 0.15) of 820 is 697.
0.15 * 820 = 697
697 = 697
Thus, we've correctly identified the original price.
