Janice Doe consumes two goods, X and Y. Janice has a utility function given by the expression:

U = 4X^0.5Y^0.5 .

So, MUX = (2Y^0.5)/(X^0.5)and MUY = (2X^0.5)/(Y0.5)

. The current prices of X and Y are 25 and 50, respectively. Janice

currently has an income of 750 per time period.

a. Write a expression for Janice's budget constraint.

b. Calculate the optimal quantities of X and Y that Janice should choose, given her budget constraint.
