Answer 1

p = 3q + 40

Explanation:

Let p = total # of points earned and q = # of questions.

We know that she gets 3 points for every question she answers correct. So the total # of points earned can be represented by 3q

We also know that she for sure earned 40 points from the essay.

If we add the two together then we get the total number of points earned on her test.

In other words p = 3q + 40
