The new president of Miskatonic University has decided on building a pool. She sat down with the contractor and together they determined what activities would have to occur, their precedence relationships, and estimated durations (in weeks). However, after a review it appeared that construction would interfere with the start of the Fall semester. Miskatonic asked the contractor to present time and cost estimates for crashing the project. The data are listed below. Activity A B C D E F G H I Predecessor - A A A B B C D F, G E, I, H Normal Time 6 3 9 10 4 2 12 3 14 4 What activity has the greatest weekly cost for crashing?
