Question

Roger is paid $50 to sell videos of a play to an audience after the play is

performed.
He also receives $2 for each video he sells. The function E(v)=50+2v
models the amount of money Roger earns by selling v videos. The play's audience
consists of 230 people and each audience member buys no more than 1 video.
What is the practical domain of the function? Show how you
determined/defined the practical domain.What is the most that Roger
can earn?

Answer 1

0 ≤ v ≤ 230

Explanation:

The function E(v)=50+2v models the amount of money Roger earns by selling v videos.

Roger is paid $50 to sell videos of a play to an audience after the play is performed. He also receives $2 for each video he sells.

Now, it is given that the play's audience consist of 230 people and each audience member buys no more than 1 video.

Therefore, the domain of the function will be given by

0 ≤ v ≤ 230

here v = 0 when each audience buys zero video and v = 230 when each audience buys 1 video. (Answer)
