Part A:

I can round 397 to 400.
I can round 132 to 130.
I can round 246 to 250.

Part B:
To estimate how many points Michael has now, we can add 400 (the rounded value of his Level 1 score) to 130 (the rounded value of his Level 2 score) and then subtract 250 (the rounded value of the points he lost on Level 3). This gives us:

400 + 130 - 250 = 280

So, the answer is A. 280.

Yes, that's correct! By rounding the scores and estimating the points lost, we can estimate Michael's total points to be 280.
