Hi there,

I'm hoping that this is the proper place for this post, and if not, please accept my apologies up front. Really, I'm so bad at math that I'm not even sure that what I want to do is possible... so here goes...

I am in need of a formula that would calculate the following scenario: I have a contest whereby contestants can earn additional points by rating other contestants. These reward points would be awarded for every 10 votes (clarification, a vote is a rating), but for every hundred votes the amount that is awarded increases by .5, so you have something that looks like this: votes -- points

001-100 = 1.0

101-200 = 1.5

201-300 = 2.0

301-400 = 2.5

...

Thus, 125 votes is worth 13 points ((100 / 10 * 1) + (20 / 10 * 1.5), 284 votes would be worth 41 points. So I am trying to find a formula that I could simply plug in the number of votes and it would return the contestant's score. Any help would be sincerely appreciated.

TIA.
