Answer:
Explanation:
The revenue function is given to you, it's just not given in equation form. In equation form, the function is
R(p) = p(120 - 4p)
If we are looking for the number of tickets that causes the revenue to be $0, we replace R(p) with 0 and solve for p.
0 = p(120 - 4p). That means, by the Zero Product Property, that
p = 0 or 120 - 4p = 0 which gives us, when we solve each one of those equations, that
p = 0 or
120 = 4p and
p = 30. The reasoning is the bold statement up above.
The equation we would use to determine the number of tickets needed to sell for the revenue to be $600 will be
600 = p(120 - 4p)
