3. The processing of Q onh'ne orders can be done using hours of robot time (denoted by If} and hours of human time [denoted L). The processing of Q = 300 online orders requires either 4 hours of robot time (L = U and K = 4) or 20 hours of human time [L = 20 and K = 0). Hours of robot time and hours of human time are perfect sub stitutes; for example, the processing of Q = 300 online orders could also he done using K = 2 hours of robot time and L = ll] hours of human time. (:1) Determine 4 points on the Q = 601] isoquant. [b] 'Write out the equation for the production function Q (L, K )- (c} Determine the labor and capital demand in terms of Qg, we and r.
