Time left $0$:$39$:$30$

If the indirect costs for each duration are $$300$ for $27$ weeks, $$240$ for $26$ weeks, $$180$ for $25$ weeks, $$120$ for $24$ weeks, $$60$ for $23$ weeks, and $$50$ for $22$ weeks, compute the direct, indirect and total costs for each duration.

$-$What is the optimum cost$-$time schedule?

The customer offers you $$10$ for every week you shorten the project from your original network.

Would you take it$?$ If so for how many weeks?
