Question

a telephone technician charges $30 per hour plus a $45 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

Answer 1

The total cost is the sum of the hourly rate and the service charge:

$Cost_{total}=Hourly+Service$

$C_{t}=H+S$

The hourly charge is the product of the hourly rate and the total time:

$Hourly=Rate \times Time$

$H=Rt$

Combining these we have:

$C_{t}=Rt+s$

Substituting the given values:

$C_{t}=(\frac{\ 30}{hour})(6.5hours)+\ 45$

$C_{t}=\ 195+\ 45$

$C_{t}=\ 240$

The total cost is $240.

Answer 2

6.5 hora would equal to $195 plus the $45 service charge, it brings the total to $240
