I apologize, I got mixed up because I was looking at similar problem with different numbers.
Here is my work for this problem.
1)
The minimum number of deluxe seats you could sell is 6, so that’s what we’ll use for the maximum profit. They make $35 off of each of those seats so
6 * 35 = $210
That leaves 24 economy seats, with a profit of $40 per seat. Since the maximum number of passengers aloud on each boat is 30, subtract that from 6 deluxe seats. You have 24 spots left open, so we’ll sell 24 economy seats, which will meet your minimum of 1 economy seat.
24 * $40 = $960
Add $210 and $960 to get $1,170 which is the maximum profit from one tour.
