To calculate how much money Riley needs to earn, we need to add the sales tax to the price of the jacket. The sales tax is 7.25% of $49.99.
7.25% of $49.99 = 0.0725 * 49.99 = $3.624275
Rounding to the nearest dollar, Riley needs to earn $3.62 in sales tax along with the price of the jacket.
So he needs to earn $49.99 + $3.62 = $53.61
Rounding to the nearest dollar, Riley needs to earn $54.
Therefore, the correct answer is D. $54.
