8 - 4(-x + 5)
As you already know, in order to find the equivalent expression to our already given one, we have to simplify it first :)
8 +4x - 20
**Remember that a negative times a negative is always a positive!!**
Add like terms.
4x + (8 - 20)
Simplify.
4x + (-12)

Answer:
$44.49
Step-by-step explanation:
The total cost before tax will be ...
$49.96 +49.96 + 0.50(49.96) = $124.90

Then the average cost per shirt for the 3 shirts is ...
$133.77/3 = $44.59
The mean cost of a shirt is $44.59.
