I answered the question but it says it is wrong.

Question

you happen to notice that the 8% sales tax that your father paid on his new luxury boat came to $3,800. How much must the car itself have cost him?

My answer for this question was: 3.518.18

Answer 1

The question indicates that the 8% sales tax is equal to $3,800 and is asking you to find the original pre-tax price (P) of the boat/car.

$3,800 = 8% of P

8% in decimal form is 0.08

3,800 = 0.08 * P

P = 3,800 / 0.08

P = $47,500

Answer 2

8% of the cost is $3800

0.08x = 3800

x = $47500
