Based on the cost of the additional work and the amount gained from selling, Savion should sell the car now for $3,800.
If Savion were to add the additional work, his profit would be:
= 5,800 - 2,400
= $3,400
This is less than the $3,800 he could make from selling the car now so his best course of action is to sell the car for $3,800 to get a larger profit.
The previous cost of $4,000 is a sunk cost so is not relevant to the calculation.
