Answer:
The max. revenue is $57,121.
This happens with 239 passengers.
The price of the ticket is $239 per person.
Step-by-step explanation:
Let the variable "P" denote the number of passengers.
If P=180, then the ticket cost is $298/person. Then the price is reduced by $1 for each additional person.
In general, if P=(180+x), then the ticket cost becomes (298-x) per person.
The revenue can be defined as the ticket cost multplied by the number of passengers:

We can derive R and equal to zero to maximize the function.

The amount of passengers is:
The price of the tickets is

The revenue is:

Step-by-step explanation:
Let d represent the number of dimes. Then 16-d is the number of nickels, and the total value is ...
0.10d +0.05(16 -d) = 1.40
0.05d + 0.80 = 1.40 . . . . . . . eliminate parentheses
0.05d = 0.60 . . . . . . . . subtract 0.80
d = 12 . . . . . . . .dimes
(16 -d) = 4 . . . . nickels
Diane has 12 dimes and 4 nickels.
