A store sells a hoodie for $45, the sales tax rate in this state is 8%. What is the total price with sales tax applied?

The answer is $48.60.

The hoodie by itself has a price of $45. If the sales tax if 8% of the price you’d have to calculate the sales tax and add it to the net amount.

(45)(.08) = 3.60

(45) + 3.60 = 48.60

$48.60. multiply 45 by 0.08 to find the tax, which is $3.60. add the price plus the tax and you have the end price, which is $48.60

The discount is 8.70 . you dont tell us the percent of tax added so there is no way to find out, unless i'm not seeing anything. without tax its 37.70
