Question

Quizplus · Accepted Answer

First, let's find out how many points the student has earned so far:

91 + 84 + 88 + 5 = 268

To get a B (80%) in the class, the student needs to earn at least:

0.80 x 520 = 416

To determine if it is possible to earn a B or better, we need to see if the student can earn at least:

416 - 268 = 148

points on the final exam. Since the final exam is worth 150 points, it is possible for the student to earn a B or better. Therefore, the answer is B) yes.
