Question $2\mathrm{.}4$

The client of a project has requested the project team to crash $8$ hours of time. The table below provides the necessary information about the possible project crashing.

$($a$)$ What is the crash cost for $8$ hours of time$-$savings?

$($b$)$ Assume the team calls the client and asks for a project extension, reducing the amount of time they need to crash. The project team has a $\backslash (\backslash$$ $20\backslash )$ crash budget. Is the budget sufficient to crash $4$ hours of time?
