Help with calculous problem!?

McDuff Preserves expects to bottle and sell 1,800,000 32-oz jars of jam at a uniform rate throughout the year. The company orders its containers from Consolidated Bottle Company. The cost of ordering a shipment of bottles is $155, and the cost of storing each empty bottle for a year is $0.39. (ume that each shipment of bottles is used up before the next shipment arrives. Round your answers to the nearest whole number.)
