MUm/Pm = MUp/Pp [MU = marginal utility; p = plane; m = milk; P = Price]

Explanation:

Consumer Equilibrium refers to consumer's utility maximising consumption, given prices & income.

Two Goods Case (Goods 1 &2) : Equilibrium is where MU1 / P1 = MU2 / P2

Here, two goods milk & plane : Equilibrium where MUm/Pm = MUp/Pp

If MUm/Pm > MUp/Pp : It means utility (satisfaction) of per unit money spent on milk is more than that of plane tickets. So, the consumer will tend to consumer more milk - this will reduce MU from milk [DMU law], this will happen till falling MUm/Pm becomes = MUp/Pp

If MUp/Pp > MUm/Pm : It means utility (satisfaction) of per unit money spent on plane tickets is more than that of plane tickets. So, the consumer will tend to consumer more plane tickets - this will reduce MU from plane tickets [DMU law], this will happen till falling becomes MUp/Pp = MUm / Pm.
