To find out how much money Riley needs to earn, we need to calculate the total cost of the jacket with the sales tax included.
To find the amount of sales tax, we multiply the cost of the jacket by the sales tax rate:
49.99 x 0.0725 = 3.624775
Rounded to the nearest dollar, the sales tax would be $3.62.
So, the total cost of the jacket with sales tax included would be:
49.99 + 3.62 = $53.61
Therefore, Riley needs to earn $54 (rounded to the nearest dollar) to purchase the new jacket.
The answer is B $54.
