The slope of the line would be positive 5/1 instead of positive 3/1. the y-intercept stays the same.
I believe you would have to multiply both 25 and 20 and what ever number you get dived by 100 if the numbers to high multiply aging or subtract the number (if it's wrong I'm really not good at my math I'm sorry)
For Range you take the biggest number and subtract it with the smallest. So:
January = E14,000
Febuary = E9,000
March = E10,000
All Three Months = E17,000
