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.

Respuesta :

average ≤ 93

inequality = ?

Step 02:

x = score on the next test

inequality:

(82 + 89 + 91 + x ) / 4 ≤ 93
