Question 4: A contractor specializes in adding new walls to homes. Each new wall takes three steps to construct: framing, dry-walling, and painting. Each step must be completed before the next step begins and there is only one crew for each step, so they can only work on one job at a time in each of the three steps. The contractor has 4 jobs waiting to be started - details of each job can be found in the table below. If the contractor uses the Critical Ratio rule to develop a job sequence, what order will the jobs be completed in and will they all be completed on time?
