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

Answer:
600 seats
Step-by-step explanation:
We know there is 120 seats on a balcony and that is 
of the total seats, we want to find the total number of seats so,
120 seats =
We know that a whole fraction sums to 1 so for example 
120 seats =
Multiply both sides to make it a whole fraction
600 seats = 
So if there is 120 seats and that number is only of the total number of seats then the total number of seats is 600
