Machine 1 can complete a task in x hours while an upgraded machine (machine 2) needs 9 fewer hours. The plant manager
knows the two machines will take at least 6 hours, as represented by the inequality:
Which answer choice includes all solutions to the inequality and identifies which interval(s) contain viable completion times of
machine 1?
(0.3] U (9,18]; both contain viable times for machine 1
0 (0.3] U (9,18); only (9,18] contains viable times for machine 1
0 (-0,0) U (3,9) U (18,co); no interval contains viable times for machine 1
0 (-0,0) U[3,9U (18,co); but only (18,co) contains viable times for machine 1
