To reduce the project length by 3 days, we need to crash activities A, C, and E since their combined duration is the longest. Crashing activity A by 2 days will cost $600, crashing activity C by 2 days will cost $1000, and crashing activity E by 1 day will cost $900. Therefore, the total cost of crashing these activities by the required duration is $2500, which is the cheapest option.
