To determine the possible scores you can earn on the last test, we need to find the minimum score required to reach a total of at least 440 points on the five qualifying tests.

We have already scored 91, 81, 77, and 96 on the first four tests.

The total score so far is: 91 + 81 + 77 + 96 = 345

To reach a minimum total of 440 points, we need to score at least 440 - 345 = 95 points on the last test.

Therefore, the three possible scores you can earn on the last test to enter the competition are:
1) 95
2) 96 (if you want an equal or higher score than your previous highest score)
3) Any score greater than 95 to ensure a total of at least 440 points.
