Question 777251
<pre>
Profit = Revenue - Cost

Cost has two parts:
Fixed cost of operating the flight, irrespective of number of passengers = 9500
Variable cost for each passenger is not specified. Assume it is 0
So the total cost = $9500

Revenue:
Revenue from one passenger = cost of the ticket = $135
Total Revenue from n passengers = 135*n

Profit P = Total revenue - total cost = 135*n - 9500

{{{P = 135*n - 9500}}} is the linear function.

Hope you got it :)
