(ii) State and explain two factors that would cause a shift in a demand curve for concert tickets. In each case explain how the factor affects the demand curve. (30) (c) The Law of Diminishing Marginal Utility states that as more of a product is consumed, eventually each additional unit of the good provides less additional utility (marginal utility). (i) Explain two assumptions underlying the Law of Diminishing Marginal Utility. A consumer in equilibrium buys 6 health bars at 60.80 each and 9 cartons of juice at 61.50 each.
