Question 8 1 pts A rm uses capital and labour to produce output according to the following production function: q = f(K,L) = KL. It pays $15 per hour for using capital and hires labour at $20 per hour. Select all that applies: C] a) The long run output expansion path for this rm is a straight line. C] b) Marginal rate of technical substitution is given by MRTSLK = g C] c) This production function exhibits constant return to scale. C] d) Assume that the rm wants to produce 2,000 units of output. If price of capital decreases to $10 per hour, the rm will use more capital and less labour. C] e) This production function exhibits increasing return to scale; thus, the rm enjoys economy of scale. E] f) This production function exhibits constant return to scale; thus, the average cost for this rm is constant (does not depend on the output it produces)
