A production function for a good Q uses inputs of labor (L) and capital (K) and takes the form Q = LK. The wage is equal to $20 and the rental rate of capital is equal to $80. The firm has to produce a target go. Assume that K is fixed at K in the short run, what is the equation for the firm's short-run total cost curve? O SRTC = 20q. + 80K 20go 80go O SRTC = + K K O SRTC = 209 + 80K K O SRTC = 20q. + 80K K
