The answers are:

A) the revenue function is:

Revenue = X * [450 - 4 (X - 20) ]

where X = total amount of passengers

B) The revenue for 60 passengers is $17,400

60 * [450 - 4 (60 - 20) ]

60 * (450 - 160)

60 * 290 = $17,400

C) The revenue for 79 passengers is $16,906

79 * [450 - 4 (79 - 20) ]

79 * (450 - 236)

79 * 214 = $16,906
