I took the time (more like I got bored waiting to get 10 billion) to figure out an equation for the price of a plant given the number of units you currently have for that plant. By doing this, I also figured out the initial price of the plant because I forgot some of them oops. Here you go: Spoiler: Equation for price y-initial is the initial price value of the plant (can be found in the spoiler below) u is the number of units you currently have Initial values for plants: Spoiler: Initial Values Note: I am aware there are more plants than pumpkins. I don't know them or their initial values yet. Please use this information to make proper decisions depending on MPS given and price compared to other alternatives for your current balance. I want to update this thread with more information regarding the math involved, so if you want to help, please PM me here or find me on Farm King. Happy Farming! Thanks to @Unprepossessing and WitherEmpire for help so far. Maybe will add upgrade prices for all.
