Question

To get a B in​ math, Alexandria Pappas must average 80 on five tests. Scores on the first four tests were 83​, 74​, 84​, and 77. What is the lowest score that she can get on the last test and still get a​ B?

Answer 1

First you would add up all four tests scores and then divide the final answer by 4 because there was a total of four tests. Therefore Alexandria can get a score of 79.5% or higher is she wants to average with an 80% on all tests. Hope this helps.
