Given an income equation, $150=($10 x Wine) + ($5 x Crackers) and utility function: U = W0.75 * C0.25 With wine on the ‘x’ axis, and Crackers on the ‘y’ axis, answer the following:

PART A: Calculate the points on indifference curve at the optimal levels of consumption of W and C, and draw the graph. The points on the indifference curve need to be calculated. Question does not ask for a definition, but rather actual values of those points on the indifference curve.
Note: I used MUW/MUC to get points points which are when C = 7.5 and W = 11.25. Now to get points on indifference curve, the 2 optimal values need to be used in calculations, and that is what I don't know how to do.

PART B: By using graphical presentation, show whether Wine is a Normal or Inferior Good? Explain, and labeling relevant effects on the graph.

    1. (24 total points) Suppose a consumer’s utility function is given by U(X,Y) = X1/2*Y1/2. Also, the consumer has $72 to spend, and the price of Good X, PX = $4. Let Good Y be a composite good whose price is PY = $1. So on the Y-axis, we are graphing the amount of money that the consumer has available to spend on all other goods for any given value of X. a) (2 points) How much X and Y...
