The owner of a luxury motor yacht that sails among the 4000 Greek islands charges $752/person/day if exactly 20 people sign up f
Elena L [17]

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

The pair of points is on the graph of an inverse variation. Find the missing value. (1.6, 6) and (8, y) 0.03 30 1.2 0.83
ZanzabumX [31]
One may note that (1.6 , 6)  is just another way to say x = 1.6 when y = 6.

and that (8 , y) is another way to say x = 8 and y is who knows.

\bf \qquad \qquad \textit{inverse proportional variation}\\\\
\textit{\underline{y} varies inversely with \underline{x}}\qquad \qquad  y=\cfrac{k}{x}\impliedby 
\begin{array}{llll}
k=constant\ of\\
\qquad  variation
\end{array}\\\\
-------------------------------

\bf \textit{we know that }
\begin{cases}
x=1.6\\
y=6
\end{cases}\implies 6=\cfrac{k}{1.6}\implies 6(1.6)=k\implies 9.6=k
\\\\\\
\qquad therefore\qquad \boxed{y=\cfrac{9.6}{x}}
\\\\\\
\textit{when x = 8, what is \underline{y}?}\qquad y=\cfrac{9.6}{8}
