If the cost of printing the novel includes a base cost of $1,550 plus $4 per book, write a function that represents the cost of printing x copies of the book.

Total cost would be defined as (y).
now, if the base cost is 1550, then that is a constant that will not change.
They tell us that "x" is the number of books
so at $ per book, we can say that is 4x
but we need to find "y"
so...
y = 4x +1550

What are the options
