To solve this problem using proportional relationships, we can set up a proportion to find the amount of money Riley needs to earn.
Let x be the amount of money he needs to earn.
Since the sales tax is 7.25%, Riley needs to earn the total cost of the jacket plus 7.25% of the total cost.
7.25% of $49.99 can be found by multiplying 0.0725 by $49.99:
0.0725 * $49.99 = $3.62
So, Riley needs to earn $49.99 + $3.62 = $53.61.
Rounded to the nearest dollar, Riley needs to earn $54.
Therefore, the correct answer is $54.
