c$.$ The critical activities are

B$,$ D$,$ F$,$ and G

so they make up the critical path.

Part $9$

The entire project will take

$$

$14\mathrm{.}5$ days to complete. $($Enter your response rounded to one decimal place.$)$

Part $10$

d$.$ Management would like to complete the project in less than $17$ days. Management has determined that activity Upper E can be crashed $2\mathrm{.}5$days$,$ for a total cost of $$$$5$ comma $000.$ No other activities can be crashed.

After$$ crashing,

is the critical path. The entire project will take
