Answer:
7 Hours
Step-by-step explanation:
Given The lawyer charges $100 per month for a client.
Also he charges $75 per hour
Let the hours he worked for the client be x
The money the lawyer gets from the hourly charges is $75x
The total money the lawyer charged is $625
total money = monthly charges + hourly charges
625=100 + 75x
75x=525
x=525/75=7
Therefore the lawyer has to work for 7 hours to charge $625
