Question

Pls Help!!

Going into the final exam, which will count as 1/3 of the final grade, Megan had test scores of 94, 81, 87, and 93. What score does Megan need on the final exam in order to have an average of 90?

Answer 1

Megan needs a 95 to get an average of 90.

Explanation:

Add up the test scores Megan has earlier, you would get 355 as a result of all scores added. In order to get an average of 90%, you would need to accumulate 450 points which she will need to take her final exam on it. Subtract 355 from 450 to get a score of 95% in which she will need that score to average it to 90%.
