Eva, the owner of eva's second time around wedding dresses, currently has five dresses to be altered, shown in the order in which they arrived: job processing time (hrs) due (hrs from now) v 3 5 w 1 1 x 4 9 y 2 3 z 5 7 if eva uses the shortest processing time first priority rule to schedule these jobs, what will be the average number of jobs in her shop today?

To answer this question, an assumption must be made, that Eva spends 8 hours a day working. If this is the case, then Eva will complete jobs w, x, and v on day one, for a total of six hours. Since the next job (y) requires 4 hours, she will spend two hours working that day, leaving 2 more hours to go on that job. The next day she will spend 2 hours finishing job y, completing it, and finish the longest job z (hours) that day. This means she had 4 jobs on day one, and 2 jobs on day 2 for and average of 3 jobs per day.

This answer assumes an 8 hour work day, and that Eva can start a job she cannot finish that day.
