Write and solve any Quezon to find a number of pens purchased

Question

The average Of your 3 quiz grades is 17 Points. Two of your quiz grades are 14 points and 19 points.

Answer 1

The title of the problem has nothing to do with the stated problem. What is a "Quezon?" What is your question? Do you want to find the grade on the 3rd quiz? If so,

x = the grade

(14 + 19 + x) / 3 = 17

Solve for x and finish from here.
