Justin Moore has scores of 72, 67, 82, and 79 on his algebra tests.

 

A. Use an inequality to find the scores he must make on the final exam to pass the course with an average of 77 or higher, given that the final exam counts as two tests.

 

B. Explain the meaning of the answer to part a

(72 + 67 + 82 + 79 + x + x ) / 6 = 77

300 + 2x = 6*77

2x = 162

x = 81          the score he needs on his final exam to have at least a 77 average
