Josephine is taking a college course, and her professor bases the course grade on the average of 2 tests taken in the semester. She wants to know what she needs to earn on the last test to maintain her grade. Rearrange the following equation for b, where C is the average of 2 test scores, a and b.

C equals the quantity a plus b all over two

b equals two times C over a
b = 2C + a

Answer:

Hi i know im very late answering this question but i believe the correct option is: b = 2C - a

Step-by-step explanation:

I believe this is the answer because:

2C = the average of 2 test scores combined

A and B = the two scores

were trying to solve for b so what we would do to figure that out is have the average of both test scores and then subtract A which will leave you with only B. therefor the answer is B = 2C - a

hope this helped.
