Solutions

Expert Solution

Note that the total cost has increased. So, the optimal cost-time trad-off is at Step-3 i.e. 27 weeks duration with total cost = $106,200

-----------------------

Repeat step-2 but this time, just reduce the duration of 'B' by one week only.

So,

the minimum cost of achieving 30-weeks duration = $107,500
