A lawyer charges his clients a consultation fee of $500 and $100 per hour to work on a case. This is represented by the linear function C = 100x + 500. If the lawyer increases his hourly rate to $150, how much more will he make on a 10-hour case?
c= 100x +500
c= 100(10) +500
c= $1500
c=150(10) +500
c= $2000
The difference of the two is $500.00
