Given that Lori brought sunglasses and flip-flops at a half-off sale, to determine, if she spent a total of $ 21 on the two items, what was the original price of the sunglasses (taking into account that they both cost the same) will be you must perform the following calculation:
- 50 = 21
- 100 = X
- 100 x 21/50 = X
- 2100/50 = X
- 42 = X
Thus, the total price of both goods is $ 42, which, divided in half, results in $ 21 (42/2).
Therefore, the sunglasses were originally priced at $ 21.
