Answer:
Therefore, Michael's estimated current score is 597 points.
Explanation:
To estimate Michael's current score, we can round his Level 2 score up to 400 (since it's closer to 400 than to 300), and his Level 3 loss down to 200 (since it's closer to 200 than to 300).
So Michael's estimated current score is:
397 (Level 1) + 400 (Level 2) - 200 (Level 3) = 597
