It costs $58,000 to operate a type A vessel and $54,000 to operate a type B vessel for that period. (a) How many of each type of vessel should be used to keep the operating costs C to a minimum? at (x, y) (b) Suppose C cx+54,000y, Find the range of values that the cost of operating a type A vessel, the coefficient c of x, can assume without changing the optimal solution. The minimum is C = SCS (c) Find the range of values that Requirement 1 for deluxe cabins can assume. (Requirement 1 pertains to the deluxe cabin requirement.) (Requirement 1) S (d) Find the shadow price for Requirement 1 for deluxe cabins. (Round your answer to the nearest cent.)
