3. Suppose the two goods, X1 and X2, are perfect substitutes at the ratio of 1 to 2 - each unit of X1 is worth, to the consumer, 2 units of X2. The consumer had an income of $100. P1=5, and P2=3. Find the optimal basket of this consumer. 4. Suppose we have two consumers in the market. Joe has the following demand curve: P-10-Q1. Lucy has the following demand curve: P-10-3Q2. Find (algebraically) the formula for the market (or aggregate) demand curve. Draw all 3 curves on 3 separate graphs that should be drawn next to each other (so I can see the horizontal summation of quantities). Joe: 5. Suppose the two goods, are perfect complements at the ratio of 1 to 1. P1=10 and P2-40. I-1000. Find the optimal basket for this consumer, and graph it (including the budget line and the relevant indifference curve)
