Answer:
20 passengers at $960 each
Step-by-step explanation:
Assuming at least 20 people sign up for the cruise, determine how many passengers will result in the maximum revenue for the owner of the yacht.
(a) Find a function R giving the revenue per day realized from the charter.
R(x) =
(b) What is the revenue per day if 48 people sign up for the cruise?
$
(c) What is the revenue per day if 78 people sign up for the cruise?
$
revenue (R) = (20+x)(960-8x)
= 19200 - 160x + 960x -8 x^2
dR/dx = -160 + 960 - 16x = 0 for a max of R
16x = 800
x = 50
-0.8* 10.8x= -8.64x
-0.8* -20= 16
-0.8* 3.2x =-2.56x
so it is equivalent to the expression -8.64x+16-2.56x but add like terms so it becomes -8.64x-2.56x+16. The final answer is -11.2x=16
