Profit per unit for the base$-$case: $

Profit per unit for the worst$-$case: $

Profit per unit for the best$-$case: $

b$.$ Construct a simulation model to estimate the mean profit per unit. If required, round your answer to the nearest cent.

Mean profit per unit $=$$

c$.$ Why is the simulation approach to risk analysis preferable to generating a variety of what$-$if scenarios?
