3. In order to become a member of the library-all-star-members club, there is a $40 sign-up fee and a $2 monthly fee. Write an equation in slope-intercept form that models this situation. Y=2x+40 4. Use equation you wrote in problem 3 to find the total cost of being an all-star library member for 19 months.

$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!

$78

Step-by-step explanation:

Y = 2X + 40

X = 19

Y = 2(19) + 40

Y = 78
