Rework problem 24 in section 1 of Chapter 7 of your textbook, about the Columbus Cruiselines, using the following data. Assume that the Nina has 550 regular cabins and 160 deluxe cabins; that the Pinta has 410 regular cabins and 420 deluxe cabins; and that the Santa Maria has 810 regular cabins and 540 deluxe cabins. Assume also that during the season there will be a demand for 11200 regular cabins and a demand for 7100 deluxe cabins. Assume also that the cost of operating the Nina for a week is $117000, that the cost of operating the Pinta for a week is $116000, that the cost of operating the Santa Maria for a week is $178000. For how many weeks should each ship be scheduled in order to meet the demand at minimum cost

1. alwaysrain irrigation, inc. would like to determine capacity requirements for the next four years. currently, two production lines are in place for making bronze and plastic sprinklers. three types of sprinklers are available in both bronze and plastic: 90-degree nozzle sprinklers, 180-degree nozzle sprinklers, and 360-degree nozzle sprinklers. management has forecast demand for the next four years as follows: both production lines can produce all the different types of nozzles. the bronze machines needed for the bronze sprinklers require two operators and can produce up to 12,000 sprinklers. the plastic injection molding machine needed for the plastic sprinklers requires four operators and can produce up to 200,000 sprinklers. three bronze machines and only one injection molding machine are available. what are the capacity requirements for the next four years? (assume that there is no learning.)
