normal time (in minutes) and normal cost ($), and crash time (in minutes) and crash cost ($) is given for each task as follows: TASK NORMAL NORMAL CRASH TIME COST TIME 15 150 15 25 250 20 30 300 27 15 150 15 150 20 200 20 A B C D E F G H 10 200 500 12 12 15 15 10 CRASH COST 150 300 350 200 200 300 300 500 a. Formulate an appropriate crashing model to achieve a completion time of 48 minutes. (10 points) b. Use Excel to determine which tasks should be shortened to achieve this goal and by how much? (6 points) c. How much will it cost to achieve this goal?
