Answer: 93
Explanation:
Firstly, we need to know the rural.scire for the 4 tests. Since the mean for the 4 tests is a 92, the total score will be:

Since we want to know the score for he 4th test, we add the score for the 3 tests that she remembers and subtract from 368. This will be:
= 368 - (100 + 95 + 80)
= 368 - 275
= 93
She had 93 in her last test.
