You are assigned your first project and if things go well you should get promoted. The CEO is aware of this project, so you have a chance for high visibility. You want to do a good job! Your first task is to define the work break down structure by interviewing project activity managers and the firm's friendly, yet boring, accountants to get "good estimates" of project activity times and costs. For one of the activities, the normal time is seven weeks, crash time is three weeks, the normal cost is $7,600, and the crash cost is $17,990. What is the crash cost per week? Round your answer to the nearest dollar. $ 9 per week
