Answer:
Practical Domain is the set of x values which are from zero to 230.
The maximum he can earn is $510.
Step-by-step explanation:
Domain is the set of x values. In this equation it is the number of videos sold that could be between zero and 230 ( considering the maximum number of people buying videos are 230).
It can be written as v lies between zero and 230 or in other words [0,230].
The maximum he can earn is
E(v)=50+2v
E(230)=50+2(230)
50+ 460= 510$
