Question 1 0.5 pts Figure 21-18 Quantity of M&M's 10 9 10 Quantity of Skittles Refer to Figure 21-18. Assume that the consumer depicted in the figure has an income of $20. The price of Skittles is $2 and the price of M&M's is $2. The consumer's optimal choice is point O A . O B. O C. OD.Question 2 0.5 pts Figure 21-16 IC1 IC2 IC3 Refer to Figure 21-16. When the price of X is $6, the price of Y is $24, and income is $48, Steve's optimal choice is point C. Then the price of Y decreases to $6. Steve's new optimal choice is point O A. O B. O D. O E.Question 3 0.5 pts Figure 21-18 Quantity of M&M's 10 9 10 Quantity of Skittles Refer to Figure 21-18. Assume that the consumer depicted in the figure faces prices and income such that she optimizes at point B. According to the graph, which of the following would cause the consumer to move to point A? a decrease in the price of Skittles a decrease in the price of M&M's an increase in the price of Skittles an increase in the price of M&M'sQuestion 4 0.5 pts Figure 21-15 Refer to Figure 21-15. The price of X is $5, the price of Y is $20, and the consumer's income is $40. Which point represents the consumer's optimal choice?
