A plumber charges $50 per hour plus $75 service fee. Jackson hired a plumber to fix a leaky sink. What are the total charges of the plumber took 3 1/2 hours to complete the repairs
We know that 1/2 as a number is 0.50 so [tex]3\frac{1}{2}[/tex] is 3.50. Multiply [tex]3\frac{1}{2}[/tex] by 50 (hourly fee) and you will get $175 for 3 1/2 hours of work
Add $175 and the $75 service fee and you will get $250 as your total. This is your answer.
