A defense attorney charges her client $4000 plus $120 per hour. The formula R=120n+4000 gives her revenue in dollars for n hours of work? What is her revenue for 100 hours of work?
R(100) = 120*100 + 4000
R(100) = 12000 + 4000
R(100) = 16000
-------------------------------
What is her revenue for 101 hours of work?
R(101) = 16120
---------------------------------
By how much did the one extra hour of work increase the revenue.
Ans: $120
( the increase in revenue is called marginal revenue for the 101st hour.) please help I can't find the answer to this it confuses me cause I'm thinking that this should be graphed...but I have a similar problem so maybe if i get this one with help i can do the other on my own thank you for taking the time to help me.
