The fleet has two types of vessels: A type A vessel has 60 deluxe cabins and 160 standard cabins, whereas a type B vessel has 80 deluxe cabins and 120 standard cabins. Under a charter agreement with odyssey travel agency, paradise river cruises is to provide odyssey with a minimum of 460 deluxe and 780 standard cabins for their 2 week cruise in may. It costs $58,000 to operate a type A vessel and $75,000 to operate a type B vessel for that period. How many of each type vessel should be used to keep operating costs to a minimum? \r<BR>\n" );
