Question

Alex received an 82, 89, and 91 on three tests. How many points does he need to score on his next test in order to have an average of at least a 93? Write an inequality that best represents this situation.

Answer 1

In this case, we'll have to carry out several steps to find the solution.

Step 01:

test scores = 82, 89, and 91

average ≤ 93

inequality = ?

Step 02:

x = score on the next test

inequality:

(82 + 89 + 91 + x ) / 4 ≤ 93
