PROBLEM II. Charlie likes apples and bananas. He consumes nothing else. The consumption bundle where Charlie consumes 21 units of apples and 12 units of bananas is written as (1, 12). The set of consumption bundles (X1, 12) such that Charlie is indifferent between (X1, 12) and (5, 15) is the set of all bundles such that 12 = 75/T1. The set of bundles (11, 12) such that Charlie is just indifferent between (21, 12) and the bundle (5, 50) is the set of bundles such that 12 = 250/1. Q6. True or false: (5, 15) ~ (25, 3). (a) True. (b) False. Q7. True or false: (10, 25) ~ (5, 15). (a) True. (b) False. Q8. True or false: (50, 4) > (30, 10). (a) True. (b) False. Q9. What is Charlie's marginal rate of substitution at the point (5, 15)? (a) -3/25. (b) -1/3 (c) -1. (d) -3. (e) -25/3. Q 10. what is charlies marginal rate substitution at the point ( 18, s ) ? (a) -3/25. (b) -1/3. (c) -1. (d) -3. (e) -25/3. Q11. What is Charlie's marginal rate of substitution at the point (25, 3)? (a) -3/25. (b) -1/3. (c) -1. (d) -3. (e) -25/3
