Other expenses = Expenses food, gifts and accommodation =
= $ 80 less than 3 times Airfare
= 3 * Airfare - $80
Total Expenses = Airfare + Other expenses
= Airfare + 3 * Airfare - $80 = $2, 660 as Given
4 * Airfare - $80 = $2, 660
4 * Airfare = $80 + $2, 660 = $2, 740
Hence, Airfare = $2, 740 / 4 = $685
= $ 80 less than 3 times Airfare
= 3 * Airfare - $80
Total Expenses = Airfare + Other expenses
= Airfare + 3 * Airfare - $80 = $2, 660 as Given
4 * Airfare - $80 = $2, 660
4 * Airfare = $80 + $2, 660 = $2, 740
Hence, Airfare = $2, 740 / 4 = $685
