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

i would say b) is your answer

sorry if im wrong

step-by-step explanation:

well if he bought them at 5 cedis each sold them at 7 cedis each then he would make a profit of 2 cedis of each book. if in total he made 150 cedis profit that means he sold 75 books. he lost 12 books at the start so that means he originally bought a total of 82 books.
