Genesis would like to join a Book Club. She needs to pay $12.00 for entrance into the book club and $20.00 per month. Write an equation in function notation for the total cost of the book
club.

An equation in function notation for the total cost of the book  club will be:

Step-by-step explanation:

Given that Genesis needs to pay $12.00 for entrance into the book club.

Per month fee = $20.00

We know that the slope-intercept form of a linear function is

where m is the slope and b is the y-intercept

As the rate of change is also called the slope.

The rate of $20.00 per month would be termed as the slope = m = 20

One time fee = $12.00, meaning the y-intercept = b = 12

Thus, the equation becomes

y = 20x + 12

Therefore, an equation in function notation for the total cost of the book  club will be:
