Jennie charges $200 per passenger for a sunset sailing
tour on her catamaran, while Paul charges $250 per
passenger. We can define the amount of money each
person earns per cruise as a random variable.
Let A = the amount of money Jennie earns and let B =
the amount of money Paul earns.
What is the mean of the sum and the mean of the
difference of the amount of money that Jennie and
Paul earn on a randomly selected cruise?
MA+B= $
HA-B = $
A = 200X and B = 250Y

The mean of the sum would be as follows:

1692.5

The difference of the amount of money earned by Jennie and Paul would be:

-232.5

Mean

Given that,

Money earned by Jennie(A) [tex]= 200X[/tex]

Money earned by Paul(B) [tex]= 250Y[/tex]

μ[tex]_{A}[/tex] = $[tex]730[/tex] & σ[tex]_{A}[/tex] = $ [tex]192.62[/tex]

μ[tex]_{B}[/tex] [tex]=[/tex] $[tex]962.5[/tex] & σ[tex]_{B}[/tex] [tex]=[/tex] $ [tex]253.425[/tex]

So,

The mean of the sum [tex]= 1692.5[/tex]

The difference of the amount of money [tex]= -232.5[/tex]
