Question

You have a coupon for $5 off an oil change. When you arrive at the auto repair

Answer 1

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
