Answer to Question 1

The first income level was 4 + 40 = 44. The second income was 30 + 27 = 57. However, at the old prices he could have consumed (5,3 ) and paid only 21, so this indicates that he prefers the first bundle. However, he could have consumed the old bundle at the new prices and paid only 20 + 24 =54, which indicates he prefers the second bundle. Thus a contradiction and his preferences are not consistent

Answer to Question 2

False. The price of the limited input will be bid up until zero economic profits result in the market that uses the input.
