Answer: A. $48.15
Explanation:
To find the total including sales tax, we must ADD the sales tax to the price of the skirt.
So how much is the sales tax for the skirt?
Well,
7% sales tax can be written as a decimal:
.07
We multiply the cost of the skirt by 7% or .07
So, $45 × 7% OR 45×.07
=3.15
Which means that 7% of $45 is $3.15.
Finally we ADD
$45.00 + $3.15
=$48.15
