The plumber's 2 hour and 26 min plumbing bill cost is $73
What is the plumber's per minute rate?
The plumber's per minute rate is the per half-hour rate divided by 30 minutes since the plumber charges $15 for every 30-minute job
per-minute rate=$15/30
per-minute rate=$0.50
Now, let us convert 2hours and 26 minutes to minutes, in other words, every 1 hour is 60 minutes, the two hours equal 120 minutes plus the 26 minutes gives a total of 146 minutes
Total minutes=120 min+26 min
total minutes=146 minutes
Total plumbing bill cost for 146 minutes is $0.50, the per-minute rate multiplied by the number of minutes the plumber needs to work in this case
2 hour and 26 min plumbing bill cost=146*$0.50
2 hour and 26 min plumbing bill cost=$73
