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.
A. $50
B. $54
C. $3.64
D. $82
To find out how much money Riley needs to earn, we'll calculate the total cost of the jacket after adding the sales tax.
First, we'll find the amount of sales tax. To do this, we'll multiply the price of the jacket ($49.99) by the sales tax rate (7.25%), which can be expressed as a decimal (0.0725).
Sales tax amount = $49.99 * 0.0725 = $3.62 (rounding to the nearest cent)
Next, we'll add the sales tax to the price of the jacket to find the total cost.
Total cost = $49.99 + $3.62 = $53.61 (rounding to the nearest cent)
Therefore, Riley needs to earn $54 to purchase the new jacket.
The correct answer is B. $54.
