Suppose that the function f(p) = 3p + 30 represents the number of points you earn on a test for getting p questions correct. you earned 13 extra credit points for a project. how many questions must you answer correctly to earn an a (90 points) on the test

p = 20 questions

Step-by-step explanation:

In order to earn 90 points on the test; equate the function to the total points to earn which is 90

3p + 30 = 90

Collect like term

Divide through by 3

Therefore, 20 questions must be answered correctly to earn 90 points.

To check,

Since p = 20, substitute p into the function thus:

Note that additional 13 points earned on project is not relevant to the calculation of the points earned on the test.
