1. The ABC Company is both a producer and a user of brass couplings. The firm operates 220 days a year and uses the couplings at a steady rate of 60 per day. Coupling can be produced at a rate of 200 per day. Annual storage cost is $2 per coupling, and machine setup cost is $110 per run. Determine the:
