Assume you are sequencing jobs using Johnson’s rule. There are three jobs called A, B and C. The first step in assembling and the second step is painting. Job A requires 3 hours to assemble and 6 hours to paint. Job B requires 7 hours to assemble and 2 hours to paint. Job C requires 4 hours to assemble and 1 hour to paint. The objective is to minimize the total processing time of all jobs, using Johnson’s rule. What is the completion time of the last job in the sequence in the second step (painting)?
