"To remain on financial aid, Millie needs to complete an average of at least 7 credits per quarter each year. In the first three quarters of 2017, she completed 5, 7, and 8 credits. How many credits of course work must Millie complete in the fourth quarter if she is to remain on financial aid?"'

Respuesta :

Answer

8:

Step-by-step explanation:

Firstly, we can see that the average number of quarters she is to complete is 7.

Since we have 4 quarters to complete, the total quarters she is to complete is 4 * 7 = 28 quarters. It means that the total number of quarters she is required to complete to stay on the financial aid is 28

Now, she has completed the following 5,7,8 quarters. To stay on the financial aid after the last quarter, she has to complete the following: 28 -5-7-8 = 8 quarters
