$90
Step-by-step explanation:
A=lw
A=20x20
A=40 ft²
40x2.25=$90
The function that represents how much you would pay is:
p(x) = (x - $5)*0.9
<h3>
How to find the function?</h3>
Let's say that the cost of the repair is x.
First, we apply the coupon, so we discount $5 for the cost.
x - $5.
Then we apply another discount of the 10%, this is written as:
(x - $5)*(1 - 10%/100%)
(x - $5)*(1 - 0.1)
(x - $5)*0.9
Then the function that represents how much you would pay is:
p(x) = (x - $5)*0.9
