The average of his grades so far is: 77%

C grade: 75%-80%

Im not sure what "what grade would he need..." means, so I am guessing you mean percentages. Just test each of the integer degrees from there and you will get the span of percentages that will work to get him a C.

Any grade between 65% and 94% on the 6th test will give you an average ranging from 75% to just under 80%.
