The revenue from selling movie tickets is given by the function R(t) = 10t, where "t" is the number of tickets sold. The theater holds a maximum of 200 people. The profit is a function of the revenue "R" and is given by the function P(R) = 0.20R. What is the domain of the profit function P(R)?
A){0, 1, 2, 3, ... , 200}B){0, 10, 20, 30, ... , 2000}C){any nonnegative real number ≤ 200}D){any nonnegative real number ≤ 2000}
