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)
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.
