Question

. TEST SCORES Benjamin's test scores for the quarter so far are 78, 82, 95, and 88. What does he need to score on the fifth test of the quarter in order to have an average test score of 87?​

Answer 1

(78+82+95+88+x)/5 = 87
So 78+82+95+88+x = 87*5
x = 435 - 78 - 82 - 95 - 88
x = 92
He need to score a 92
