Answer:
size of group is 53 people
Explanation:
given data
person = 42
per person pay = $64
to find out
size of the group that maximizes income for the owners of the ship
solution
we will consider here number of additional person is = x
so
total passenger = x + 42
and price per person = 64 - x
so
total income is
R ( x) = ( x + 42 ) × ( 64 - x )
R ( x) = −x² + 22 x + 2688 .......................1
and maximize the total income will be when R (x) is a quadratic function
so
f (x) = ax² + bx + c is maximum
when a ≤ 0 and x =
so
income will maximum when x from equation 1
x =
x = 11
so
size of group is 42 + 11 = 53
