We have the following ratio: 


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


So in this case, the ratio is:

200%2F1=x%2F39


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



200%2F1=x%2F39 Start with the given ratio


%28200%2F1%29%2A39=x Multiply both sides by 39


7800%2F1=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.
