Use proportional relationships to solve the following problem. Riley needs to eam 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 eam? Round to the nearest dollar. (1 point)

1 answer

To find out how much money Riley needs to earn, we need to calculate the amount of the state sales tax on the jacket.

Let's set up a proportion:

7.25/100 = x/49.99

Cross multiply:

100x = 49.99 * 7.25

Divide both sides by 100:

x = (49.99 * 7.25)/100

Multiply:

x = 362.4375

Rounded to the nearest dollar, Riley needs to earn $362.
