George has spent $600 purchasing and repairing an old fishing boat, which he expects to sell for $900 once the repairs are complete. George discovers that, in addition to the $600 he has already spent, he needs to make an additional repair, which will cost another $400, in order to make the boat worth $900 to potential buyers. He can sell the boat as it is now for $400. What should he do?
A.
He should sell the boat as it is now for $400.
B.
He should keep the boat since it would not be rational to spend $1,000 on repairs and then sell the boat for $900.
C.
He should complete the repairs and sell the boat for $900.
D.
It does not matter which action he takes; the outcome is the same either way.
