Answer:

A score between 84 and 99

Step-by-step explanation:

First, let's solve for what you would need to score on your next test to have an average of 84:

(81 + 87 + x)/3 = 84

(168 + x)/3 = 84

168 + x = 252

x = 84

Next, let's solve for what you would need to score on your next test to have an average of 89:

(81 + 87 + x)/3 = 89

(168 + x)/3 = 89

168 + x = 267

x = 99

That means you would have to earn a score between 84 and 99.

I hope this helped you, and if it did, a brainliest would be appreciated :)
