Answer:
Megan needs a 95 to get an average of 90.
Step-by-step 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%.
Oh Yes It Does Yes It dose
She spent 10 minutes. 25% x 40 = 10.
