Question

Options:
$3.62
$50
$82
$54

Answer 1

To solve this problem using proportional relationships, we can set up the following equation:

49.99 + (49.99 * 0.0725) = x

49.99 represents the cost of the jacket. To find the total amount he needs to earn, we also need to add the amount of state tax, which is calculated by multiplying the cost of the jacket (49.99) by the tax rate (0.0725).

Calculating this equation, we get:

49.99 + (49.99 * 0.0725) = 54.014775

Rounded to the nearest dollar, Riley needs to earn $54 to buy the jacket.

Therefore, the answer is $54.
