196349 Mushroom cultivator program

This is pretty easy stuff. I need a basic program made that will allow the following: -Calculate the date of final mushroom maturity based on a few variables -Let users calculate how much of a few certain supplies are needed (have formula) -Calculate the dry weight of an inputted amount of mushrooms -Allow users to log and save weights of their mushrooms Attached is a file describing in better detail what I need. Thank you
