c) Bragg’s loses $3,500 in profit per week for every week
the bakery is not completed. How many weeks will the project
take if the bakery is willing to pay the crashing cost as long as
it is economically the right decision?
d) What is the project completion time if all activities are
crashed to their minimum Crash Time? Also, ignoring the
$3,500 lost profit in c), what is the total additional cost
incurred for crashing all of the activities to their minimum Crash
Time compared to the Normal Times?
