Minimizing Transportation Cost. Suppose that in the preceding problem a new airplane P3 becomes available, having an operating cost for the same trip of $15 thousand and accommodating 40 first-class, 40 tourist-class, and 80 economy-class passengers. If airplane P1 were replaced by airplane P3, how many of P2 and P3 should be used in order to minimize the operating cost? What is the minimum operating cost?
