A telephone technician charges $30.00
per hour plus a $45.00 service charge.
Your father's firm hires him to hook up his company's phone system.
Find the total charges if it takes the telephone technician 6.5 hours to complete the task
To find the total charges, we need to calculate the cost of the technician's time and the service charge.
The cost of the technician's time is $30.00 per hour for 6.5 hours, which is 30 * 6.5 = $<<30*6.5=195>>195.
The service charge is $45.00.
Therefore, the total charges are $195 + $45 = $<<195+45=240>>240. Answer: \boxed{240}.
