I have no idea what 624 is or means but I assume it is money or some kind of counting (but I don't know how one models money :-)].

Ali could have used 5 hundreds, 6 twenties, and 4 ones (no tens).

If I have interpreted incorrectly, please repost and clarify.

Well, I have been out of 3rd grade for awhile, but i am in middle school:)

I think Ali could use 6 hundreds, and 24 ones. Therefore turning the 2 tens into ones (2x10= 20) and adding the ones she already had (20+4=24)

~Hope I helped;)
