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? A) $250 B) $500 C) $750 D) $1000

Respuesta :

The difference between his old hourly rate and his updated hourly rate is $50

10 hours with $50 more dollars per hour

10*50=500

The lawyer is making $500 more dollars for 10 hours
B is your answer.  100x10 is 1000 +500 =1500 and 150x10 is 1500+500 = 2000.
