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 = $
V
A = 200X and B = 250Y
MA= $730, A = $192.62
Ha = $962.5, 0.= $253.425
