I am doing a project where I need to get this info:

For every 5 buildings that are torn down, 2 new businesses OR 1 new condo can be built up.

I need to be able to type in any number of businesses/condos so that I can figure out how many buildings I need to tear down and vice versa.


This is over a span of 5 years, the 5 years is a fixed rate but the rest can vary so I need a formula that can be altered.
