This project all has to do with monetization. People watch advertisements to earn points which are redeemable for cash. Recently I noticed that I was actually giving more than I was getting because of the lower CPM (I thought it was $5.00) I changed to a new system to meet those standards and make it look at bit nicer with the payouts. For example, 10,000P is worth 10 cents. But I need to transfer all the previous points from users into this new system. Mainly if a user had 150 points it would transfer to 250 points. What I gave earlier were examples of how a certain amount of points from the old system were transferred into a certain amount in the new system. This can be repeated infinitely forward. Those decimal values are U.S. Dollars down to small increments.

So overall, I would like to be able to enter any value for X and get the correct output.

The values following the equal signs are U.S. dollars to represent the fact that when the points change they must equal that amount in dollars.

150 points in the old system equals a quarter of a cent (0.0025)

250 points in the new system still equals a quarter of a cent (0.0025)
