$)$ Reconsider problem $2),$ disregarding part $2$d$)($where one of the activity times has been cut in half$).$ Assume you can decrease a total of $100\%$ off of activity times.$$ For example, you could cut activity H by $100\%$ from $5$ down to $0$; or you could cut each of the $10$ activities by $10\%(10*10\%=100\%)$; or you could cut activities D and E each by $50\%$ from $9$ down to $4\mathrm{.}5(2*50\%=100\%).$ Any combination of decreases that add up to $100\%$ is allowed.$$ What is the optimal way to allocate the $100\%$ that minimizes the total project completion time?$$ Describe how you approached this problem.
