Answer:

Total Utility is total satisfaction from all units of consumption of a good. TU= ΣMU

Marginal Utility is additional satisfaction from additional unit of consumption of a good.  MU = TUn - TUn-1

Average Utility is average satisfaction per unit of output consumed of a good. AU = TU/N

1. TU Increases at increasing rate : MU  Increases  

TU increases at decreasing rate : MU decreases

TU is maximum : MU is zero

TU is falling : MU is negative

MU > AU : AU increase

MU < AU : AU decrease

2. Consumer Optimum is where consumer gets maximum satisfaction from consumption of certain units of a good, any deviation from that yields lesser satisfaction from the optimum point.

3. Consumer Optimum is where : Marginal Utility of the good = Price of the good.

4. Q       0    1      2         3      4      5

  TU      0   60    130   190   230   250

MU at 4th unit  = TUn - TUn-1 = TU4 - TU3 = 230 - 90 = 40

AU at 3rd unit  = TU / N = 190/ 3 = 63.3

AU at 5th unit =  TU / N = 250/5 = 50
