Answer:
$118.706 or rounded to $118.71
Explanation:
Since it is on sale, find the discount price. $139 * 0.8 = 111.20
I used 0.8 because you got 20% off so it is only 80% of original price or 0.8 of original price.
Then 111.20 * (1.0675) = $118.706 or rounded to $118.71.
Tax is 6.75% or 0.0675. It is on top of the discount price, so use 1.0675.
Alternatively you can find 0.0675 * 111.20 and add that to 111.20 and still get the same answer.
