Answer:
Step-by-step explanation:
 the passengers of  hawaiian airlines  in 2018 were 1.800.000, and for Northwest airlines 192.500.000 (delta)
We replace this number in the equation :
Hawaiian : 0,990 +0.683 x (number of passengers) =
                   0.990 + 0.683 x (1.800.000) =12294012
Northwest airlines: 0,990 +0.683 x (number of passengers) =
                   0.990 + 0.683 x (195.000.000) = 131477501
