Warner Corporation purchased a machine $7$ years ago for $$345,000$ when it launched product P$50.$ Unfortunately, this machine has broken down and cannot be repaired. The machine could be replaced by a new model $300$ machine costing $$336,950$ or by a new model $200$ machine costing $$300,800.$ Management has decided to buy the model $200$ machine. It has less capacity than the model $300$ machine, but its capacity is sufficient to continue making product P$50.$ Management also considered, but rejected, the alternative of dropping product $P50$ and not replacing the old machine. If that were done, the $$300,800$ invested in the new machine could instead have been invested in a project that would have returned a total of $$400,000.$

Required:

What is the total differential cost regarding the decision to buy the model $200$ machine rather than the model $300$ machine?

What is the total sunk cost regarding the decision to buy the model $200$ machine rather than the model $300$ machine?

What is the total opportunity cost regarding the decision to invest in the model $200$ machine?
