calculate present value for future increase

[wysie218]

Hi, I have the year end percentages but there was an increase during the year. So

say I started at 60% in Jan but increased to 65% in May for the rest of the

year. At year end I would be at 65%. I have the year end number and the

amount of increase during the year and when it happened...how do I calculate

January's starting percentage?
