(NOTE: ENTER YOUR ANSWER WITHOUT COMMA, ROUNDED TO THE NEAREST TON, for instance as 5824, not as 5,824.24. Do not round intermediate calculations! Tri-State Logistics is looking to purchase a new unloading robot for one of its sites. The choice is between machine A and machine B, with both machines lasting 5 years. Machine A would cost $75,000 to purchase its operating cost would be $373 per ton of material unloaded, and it would be sold for $35,000 at the end of the 5 years. Machine B would cost $97,000 to purchase, its operating cost would be $233 per ton of material unloaded, and it would be sold for $47,000 at the end of 5 years. Assuming 9% interest rate, calculate the minimum annual number of tons of material unloaded, that would be required to choose machine B over machine A
