Use proportional relationships to solve the following problem. Riley needs to earn enough money to purchase a new jacket. The one he likes best is $49.99. His state sales tax is 7.25. How much money does he need to earn? Round to the nearest dollar.

1 answer

To find how much money Riley needs to earn including the state sales tax, we first need to calculate the sales tax amount. To do this, we multiply the jacket price by the sales tax rate as a decimal:

49.99 * 0.0725 = $3.624775

We then add this tax amount to the jacket price to find the total amount Riley needs to earn:

49.99 + 3.624775 = $53.614775

Rounding this to the nearest dollar gives us $54. Thus, Riley needs to earn $54 to purchase the new jacket.
