Savion is restoring a car and has already spent $$4,000$ on the restoration. Savion expects to be able to sell the car for $$5,800$ but needs to do an additional $$2,400$ of work to make the car worth $$5,800$ to potential buyers. Savion could also sell the car now, without completing the additional work, for $$3,800.$ What should Savion do$?$

a$.$ Sell the car now for $$3,800.$

b$.$ Complete the additional work and sell the car for $$5,800.$

c$.$ Keep the car since it wouldn't be rational to spend $$6,400$ restoring a car and then sell it for only $$5,800.$

d$.$ It does not matter which action Savion takes since the outcome will be the same either way.
