You have a coupon for $5 off an oil change. When you arrive at the auto repair
shop, you learn that the store is holding a customer appreciation sale, and all
customers will receive 10% off the cost of the repair. Write a function p (x) that
represents how much you would pay if you use the coupon first, followed by
applying the discount from the repair shop.

The function that represents how much you would pay is:

p(x) = (x - $5)*0.9

How to find the function?

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
