Answer=150 seats were on the plane total
54 81
____=____
100 x
cross multiply
54x=8100
x=150 seats
For each person the Total paid = cost of 7 fire alarms + the installation fee.
To find the installation fees consider the following: F = installation fee
Peter: 452.98 = 7(59.59) + F therefore F = 35.85
Ashley: 453.39 = 7(58,29) + F therefore F = 45.36
Now we find the difference between the two fees: 45.36 - 35.85 = 9.51
