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 * Time


H=Rt


Combining these we have:


C_(t)=Rt+s


Substituting the given values:


C_(t)=((\$30)/(hour))(6.5hours)+\$45


C_(t)=\$195+\$45


C_(t)=\$240


The total cost is $240.

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