So what do I do next
Answered by Ms. Sue
(88 + 78 + 98 + 88 + 78 + x)/6 = 79

430 + x = 474

x = 44

Ok thanks I got that when you asked me what was the highest C possible. Great to know it's correct!
I did it another way. Similar though!
I added the 5 known test scores up
88 + 78 + 98 + 88 + 78 = 430

79 * 6 = 474

474 - 430 = 44
