Hi. Please help with this question. Please refrain from AI, our teacher are very critical of us using it. Thank you so much!!

Question 1: Famous economists. (4 marks) When Paul Samuelson switched from Physics to Economics, Robert Solow is said to have remarked than the average 1Q in both disciplines went up. A bystander responded that Solow's claim must be wrong because it implies that average 1Q for academia as a whole (which is the weighted average of the average 1Q levels for each discipline) must also have gone up as a result of the switch, which is clearly impossible. Was the bystander correct? Explain. (and if you don't know who these economists are, be sure to google them and find out!) Question 2. Bargaining over the gains from exchange (4 marks) Suppose the marginal product of labour is currently equal to its average product. Imagine you are one of 10 new workers the firm 1s about to hire, why might you and your potential new employer have differing views on whether you should be paid according to your marginal product or your average product. Explain. Question 3: Graphing it out. (8 marks) If output is given by Q = 2KL, and if p, = 4 and p, = 20, and if capital is fixed at 8 units in the short run, then provide algebraic expressions for each of the following, as well as graphing then: ATC, AVC, AFC and MC. Question 4 (4 marks) A multi-product firm has two different production processes, one for good A and one for good B. The associated cost functions for each production process are given by: TC, =2Q% +10 TCy = iog 15 What is the most efficient way for the firm to produce 20 units of output
