What is her revenue for 100 hours of work?

Revenue is R=120%28100%29%2B4000=12000%2B4000=16000 dollars



What is her revenue for 101 hours of work?

Revenue is R=120%28101%29%2B4000=12120%2B4000=16120 dollars


By how much did the one extra hour of work increase the revenue?

One extra hour of work increases the revenue by 16120-16000=120 dollars.
