I have some trees and i want to get some prices for them in different years.
How can i do it?

For example: Orange trees (OT) and bananas (BA) that are 1,2,3,4,5 years
old. The prices for every type of tree is different. OT-1year - $100,
OT-2Years - $200 and BA-1year - $300, BA-2years - $400.etc.
How can i make a commant that will recognize the type of tree, its age and
give me the price that i want.
Please i really need it.
