Ellis seafood is determining which distribution option it should use next year for delivery to its commercial clients. They have an option to lease their own truck at a fixed cost of $21K per year (includes lease, insurance, and maintenance). Variable costs per delivery would be $50 per order. Currently, they are using a common carrier to deliver their orders in town. The costs to maintain the contract are estimated to be $2000 (vendor qualification / quality assurance) but the variable cost per shipment is $300.

What is the indifference point between these two options?
