For the first job requiring 45 meters of pipe, the plumber will need to buy 8 sections of pipe (45 meters / 6 meter lengths = 7.5 sections, round up to the nearest whole number).
For the second job requiring 30 meters of pipe, the plumber will need to buy 5 sections of pipe (30 meters / 6 meter lengths = 5 sections).
In total, the plumber will need to buy 13 sections of pipe.
The total length of pipe bought will be 78 meters (13 sections x 6 meter lengths).
Since the total length of pipe bought is greater than the combined length required for both jobs (45 meters + 30 meters = 75 meters), there will be 3 meters of pipe left over (78 meters - 75 meters = 3 meters).
For the second job requiring 30 meters of pipe, the plumber will need to buy 5 sections of pipe (30 meters / 6 meter lengths = 5 sections).
In total, the plumber will need to buy 13 sections of pipe.
The total length of pipe bought will be 78 meters (13 sections x 6 meter lengths).
Since the total length of pipe bought is greater than the combined length required for both jobs (45 meters + 30 meters = 75 meters), there will be 3 meters of pipe left over (78 meters - 75 meters = 3 meters).
