Claire uses farming equipment and gardeners to maintain her organic farm. Each gardener is paid $160 per week and each piece of framing equipment costs $80 per week to rent.

She can minimize her cost of maintaining 150 acres of farmland (q = 150) with 15 gardeners and 20 pieces of equipment. To maintain 400 acres of farmland at the lowest cost, she uses 30 gardeners and 40 pieces of equipment. Finally, the use of 45 gardeners and 60 pieces of equipment enables her to maintain 900 acres of farmland at the lowest cost possible.

Part a: Roughly illustrate Claire's isoquant and isocost line graph and the LRAC curve using the information above. Please label the axis and the curves, including the numerical values of axis intercepts.

Part b: What type of returns to scale (choose from: increasing, decreasing, constant) and economies of scale (choose from: economies of scale, diseconomies of scale, neither economies or diseconomies of scale) is her farm experiencing?

Part c: Suppose q = 400. How should Claire adjust her output if her objective is to produce at the minimum efficient scale?
