Math Is Fun Forum

I have several peole who are using their credit cards each month.  The current limit on the credit card is $1500.  What they are actually spending is anywhere from $220 to $890.  I want to see how the actual card spend is distributed because if for example I see 50% of people spending on average $300 then I may recommend they use a card with a lower limit.  If I see there is also another high percentage of people using the card alot (approx $700) then I may put those people on a higher limit credit card.  Is a distribution chart something that could help me with that?  If so, how would I arrange my data to be able to plot it?

Thanks in advance for any guidance!
