Question

2. Abagail has an estimated Cobb-Douglas utility function of U = 91 927 for food, 91, and housing, 92- The price for food is arbitrarily set at $1 per unit Pi = $1 and the average monthly rent near UCF, P2, is $1.50 per sq ft. Jackie, like the average UCF student spends $800 on food and housing per month (a) (20 points) Using calculus, solve for Abagail's optimal quantities of housing and food. For 10 bonus points provide the marginal utility of income (*) (b) (8 points) What is Abagail's utility at the optimal bundle?

please answer all of them i will leave tumbs up

Answer 1

We are supposed to do only four subparts to a question. For solution to other parts please post as separate question.
