Question 1073105: Ace cruiser line offers an inland waterway cruise to a group of 50 people for a price of R30 per person but it reduces the price person by R0.50 for each additional person above 50.
Define the revenue functions for the inland waterway cruise:
1. R(x) = x^2 - 20x + 1500
2. R(x) = -0.5x^2 + 5x + 1500
3. R(x) = x^2 + 80x + 1500
4. R(x) = 0.5x^2 + 55x + 1500
5. None of the above

It is a composite function 

         x*30                if x <= 50, 
R(x) =                                   and
         x(30-0.5*(x-50))    if x > 50.


No one of the options 1) - 4) is composite function, so the answer is the option 5).
