ECO 204, S. Ajaz Hussain. Do not distribute. Let number of buses/day, number of workers (labor) per day, and number of passengers/day. Denote the price of leasing (or owning) buses per day by and daily wages by (assume that drivers and conductors have the same daily wage). In this question, all inputs are variable. ( ) (a) If ABC wishes to carry passengers per day, what is the optimal (cost minimizing) number of buses and labor per day? That is,...
