Revenue = attendance x price

We have, from the description of the problem,

Attendance = c - 3000 x price, where c is a constant. When price = 10, attendance = 30000, so

30000 = c - 3000 x 10

c = 60000


a = 60000 - 3000p


R(p) = a x p

= (60000 - 3000p) x p

= 60000p - 3000p^2

To find the maximum, we need to find a turning point (where dR/dp = 0). Differentiate:

dR/dp = 60000 - 6000p

So p = 10 is a turning point. This is the maximum since the function has a negative p^2 term, so it's an inverted u-shape (with a maximum and no minima).

At p = 10, the revenue is 600000 - 300000 = $300,000.
