If a card contains the number 47229 and mrs.s picks a 7, the card is worth 7000 points. If she picks a 2 its worth 220 point.
Ashley has these cards
49298 83483 43281
If mrs.s pick a 3 how many points will she have? What digit will make he have the highest score possible?

3 will be three thousand, see the last number
4 will be the biggest score...figure out why. 
what I don't get it

looks like the point value is determined by the "place holder" value of the number.
so for 3
no points from first card
3000 + 3 from the second card
3000 from the third
for a total of 6003
picking 8 will yield the highest number of points 
thank you

What digit does she hope the teacher will pull next week so she will have he highest possible score?
