Answer to Question 1

This would be enough information. Total variable cost can be can be calculated by taking the average variable cost and multiplying times the output level. Total fixed costs can be derived by taking the average fixed costs and multiplying it times the level of output. The total cost of the firm is simply the sum of both of these figures.

Answer to Question 2

Your average would continue to fall. If you received a score on one examination that was higher than the previous exam score there wouldn't be any way to determine what would happen to your average unless you knew what this score was compared to your previous average, not your previous exam score.
