Question 170165
We have the following ratio:


<pre>

       Cost                   Cost
------------------  = --------------------
  Number of Hours        Number of Hours


</pre>


So in this case, the ratio is:


{{{200/1=x/39}}}



------------------------------------




{{{200/1=x/39}}} Start with the given ratio



{{{(200/1)*39=x}}} Multiply both sides by 39



{{{7800/1=x}}} Multiply



{{{7800=x}}} Reduce




So our answer is  {{{x=7800}}} which means that the lawyer will charge $7,800 for 39 hours of service.
