-----
Equation:
(74 + 3x)/4 = 76
----
74 + 3x = 304
3x = 230
x = 75

Ans: Your have to average 75 on the remaining 3 tests.
If you get 100 on 2 of the 3 tests, you can get 25 on the 3rd test.

You mean lowest score you can have and still make a 76% average.
Assume on two tests you get 100%.

Then you could only afford to get a 30%.
So anything lower than 100% on those two other test forces you to get a better than a 30%.
