Question

Quizplus · Accepted Answer

Jerome currently has a total of 61 + 72 + 59 + 75 + 77 = 344 points from the five tests. In order to average 70, he needs a total of 70 x 6 = 420 points.

Since the final exam counts as three tests, it will be worth 3/6 or 1/2 of his total grade.

Let x be the score that Jerome needs on the final exam. Then:

(344 + x) / 6 = 70

Solving for x, we get:

x = 72

Therefore, Jerome needs to score a 72 on the final exam to earn a C.
