please answer a-e. thank you

Dana is in charge of planning for her sorority's social events. She is currently determining the best way to supply the posters needed for upcoming social events. In the upcoming winter semester, she expects to need 550 posters. Following that, in the spring, she will need 850 posters. Finally, the summer semester will require 425 posters. If she makes a poster ahead of time, she can store it in a locker for $1.50 (holding cost) per poster per semester. She has also decided that the event must have the planned number of posters; Back-orders are not allowed. To meet these demands, utilize the Transportation Model and the following information: . make the posters 'regular time' by using members of the social committee during their normal meeting hours. Based on time and effort, each poster would cost about $13.00, and her team could make 175 posters per semester . ask the social committee to stay late, or 'overtime', to work on posters. This would cost about $19.50 per poster, based on the materials, time and a 'bribe' of pizza and drinks. This could generate up to 200 posters per semester. . outsource 'subcontract' by asking another club to help out. She would have to pay this club $25 per poster, and they could create up to 500 per semester [ Select] :J a. What are the lowest possible costs for Dana?
