Stat analysis-find the best ratio to minimize

 A dissipate-beaming force establish burns dissipate after a while abetting fuel to breed force, but beaming dissipate produces fly ash which is toxic. We entertain the monthly facts of dissipate into incinerator, breedd force, fuel into incinerator and sum of fly ash executed (all in tons) 

 How do we experience the best relative of dissipate to fuel to minimize departure ash?
