Answer:
27.83$ I believe
Explanation:
30.09 is the end price, so multiply that times 7.5% or 0.075 in decimal terms
You would get 2.25675 which is the amount of tax that was paid
So all you have to left is subtract 2.25675 from 30.09 to find the original price
or 27.83 rounded to the nearest hundredth
