If that is exactly how the problem was given to you, then we don't know how to solve it either, because "price change" is not well defined.
Grammatically, a price change of 179.17% means the price INCREASED by 179.17%; that would make the new price of $23.45 279.17% of the original price. The original price x would then be calculated as
2.7917x = $23.45
x = $23.45/2.7917 = $8.40
But it is possible that the intended information is that the new price is 179.17% OF the old price; in that case the original price x would be calculated as
1.7917x = $23.45
x = $23.45/1.7917 = $13.09
The first calculation gives a result for the original price that is much closer to a whole number than the second, so it is likely that the intent of the information is that the price INCREASED BY 179.17%.
