a) Write an expression to describe the journey of the yellow submarine.
-> ((0 - 40) + 30) - 25
[] Sea level = 0
[] The descend 40 meters = -40
[] After examining the sea, they rose 30 meters = + 30
[] They dove 25 meters to look at an octopus = -25
b) At what depth did they stop to look at the octopus?
-> -35 meters
[] The started at 0 (0), descended 40 (-40), rose 30 (-10), and then sove 25 (-35) to see the octopus
[] Another way to think of this is to simplify our previous expression completely

Answer:
$78
Step-by-step explanation:
In the equation y = 2x + 40, x represents the number of months the member is a part of the club.
We are given that a certain member is part of the club for 19 months, so we substitute the number 19 in for x:
y = 2x + 40 = 2 * 19 + 40 = 38 + 40 = 78.
Thus, the total cost is $78.
Hope this helps!
