Appendix 4B The Consumer Optimum

We can derive Equation 4.6 using calculus. Lisa’s objective is to maximize her utility, U(B, Z), subject to (s.t.) a budget constraint:

q=20 (4B.1)

where B is the number of burritos she buys at price q=15 [&p_{B},&] Z is the number of pizzas she buys at price p Z , [&p_{Z},&] Y is her income, and q=35. [&Y|=|p_{B}B|+|p_{Z}Z&] is her budget constraint. This mathematical statement of her problem shows that her choice variables are B and Z, which appear under the “max” term in the equation.

Because we cannot directly solve a constrained maximization problem, we want to convert Equation 4B.1 into an unconstrained problem by substituting the budget constraint into the utility function. Using algebra, ...
