Answer:

A score of 73

Step-by-step explanation:

Five exam scores + the final exam = mean (average) of 80.

First find the total points that you need to make an 80 average 80 × 6 = 480 points.

The five exam scores + x score = 480 points.

93 + 67 + 82 + 71 + 94 + x = 480

407 + x = 480

x = 480 - 407

x = 73
