To find how much money Riley needs to earn, we need to calculate the total cost of the jacket including sales tax.
The sales tax is 7.25% of the cost of the jacket. We can set up a proportional relationship using this information.
Let's use x to represent the total cost of the jacket, including sales tax.
7.25/100 = x/49.99
Cross multiply and solve for x:
7.25 * 49.99 = 100 * x
362.5775 = 100x
Divide both sides by 100 to isolate x:
x = 362.5775 / 100
x = 3.625775
Rounded to the nearest dollar, Riley needs to earn $4.
Therefore the correct answer is $4.
