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.
