In mathematical terms, Total utility is the direct function of the number of units of a commodity. In simple words, more of the units of a commodity is consumed; more will be the total utility. It can be written as, TU x =f(x) TU= Total utility of a commodity ‘x’ f=Function x= quantity of ‘x’commodity consumed. Again, the total utility can also be expressed with the help of marginal utility. It is the summation of all the marginal utilities , i.e. TU OR TU= MU 1 + MU 2+ MU 3 +MU 4……… +M
