Only need help with last question thank you

You manage a plant that mass-produces engines by teams of workers using assembly machines. The technology is summarized by the production function q =20KL where q is the number of engines per week, K is the number of assembly machines, and L is the number of labor teams. Each assembly machine rents for r = $30,000 per week, and each team costs w = $5,000 per week. Engine costs are given by the cost of labor teams and machines, plus $2,000 per engine for raw materials, Your plant has a fixed installation of 5 assembly machines as part of its design. he total cost of producing q units of output (TC) is 9 ) + 2,000q. TC - 5,000(700 .O B. TC = 5,000( 70) C. TC = 150,000 + 7,000q. O D. TC = 150,000 + 5,000q. TC = 150,000 + 5,000( ) + 2,000q. he average cost (AC) of producing q machines is A AC = _ 150,000 &B. -+2,000. AC = 150,000 -+ 2,050. C. AC = 150,000 +5,000( 9 ) + 2,000q. OD. AC = _ 150,000 -+50. AC - _ 150,000 he marginal cost (MC) of producing q machines is A. MC = 2,000q. B. MC =2,050. C. MC = 2,050q. O D. MC =50. E. MC = 50q low do average costs vary with output? quantity increases, average costs decrease ow many teams are required to produce 100 engines? To produce 100engines, 1.00 labor team(s) are required. (Enter your response rounded to two decimal places.) e average cost per engine will be $ 3550 . (Enter your response as an integer.) ou are asked to make recommendations for the design of a new production facility. What capital/labor ratio should the new plant accommodate if it wants to minimize the total cost of producing at any level of output q? e firm should use | units of capital for every unit of labor used. (Enter your response rounded to two decimal places.)
