The maximum profit for 1 tour would be $2650
if there are 90 seats and 10 deluxe seats must be sold, you have to multiply 10 times 25 which gives you 250.
if there are 90 seats, 10 must be deluxe (which is cheaper), and you are trying to find the max profit for 1 tour, then 80 of the seats must be economy seats.
to find out how much 80 economy seats would cost you need to multiply 80 times 30 which gives you 2400.
then you need to add the profit of 80 economy seats and 10 deluxe seats and that would give you $2650
and $2650 would be the max profit you could make for 1 tour.
Two because after you came you and that other person are still in the room
