Answer:

88%

Step-by-step explanation:

First we multiply the mean by 5.

77.4 x 5 = 387

Then we add all of the test scores.

88 + 77 + 70 + 72 = 299

We subtract the total of the scores from 387, which we got from mulitplying the mean by 5.

387 - 299 = 88

Therefore, Tom's score on his fifth test was an 88%.

Hope this helps!
