I really don't have a clue where to begin.

I really don't have a clue where to begin.

let x = final exam grade

[(2/3) * 56] + [(1/3) * x] > 70

solve the inequality for x.

Wilbert has a chance to pass with a 70, but I'd say it would be a very slim chance.

Skeeter,
Thanks for setting this problem up for me. I agree with you that he'll probably never pass with a 70!

Thanks again,
Mammy
