O togineers (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 6 years. Machine A would cost $75,000 to purchase, its operating cost would be $441 per ton of material unloaded, and it would be sold for $35,000 at the end of the 6 years. Machine B would cost $89,000 to purchase, its operating cost would be $298 per ton of material unloaded, and it would be sold for $39,000 at the end of 6 years. Assuming 9% interest rate, calculate the minimum annual number of tons of material unloaded, that would be required to choose machine 8 over machine A
