Answer:
Operating costs = $246,339
Explanation:
Given
Operating costs = $57,210 + $2,644 per flight + $5 per passenger
Expected Activity
72 flights.
280 passengers
Actual Activity
71 flights
281 passengers.
Actual operating cost = $245,290
The formula given in the question will be used and we'll take into consideration the actual events that happened in the month of February (not the expected activities).
Formula:
Operating costs = $57,210 + $2,644 per flight + $5 per passenger
Actual Activity
71 flights
281 passengers.
By substitution
Operating costs = $57,210 + $2,644 * 71 + $5 * 281
Operating costs = $246,339
