a small cruise ship that can hold up to 66 people provide three day excursions to groups of 40 or more. If the group contains 40 people, each person pays $66. The cost per person for all members of the party is reduced by $1 for each person in excess of 40. find the size of the group that maximizes income for the owners of the ship.

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
