Let y represent the total cost of publishing a book (in dollars), Let \( x \) represent the number of copies of the book printed. Suppose that \( x \) and \( y \) are related by the equation \( 25 x+1150=y \), Annaleigh Answer the questions below. \( \begin{array}{l}\text { Note that a change can be an increase or a decrease, } \\ \text { For an increase, use a positive number, For a decrease, use a negative number. } \\ \text { what is the change in the total cost for each book printed? }\end{array} \) what is the coss to get started (before any books are printed)?

The change in the total cost for each book printed is represented by the coefficient of \( x \) in the equation \( 25x + 1150 = y \). Here, for each additional book printed, the total cost increases by $25. So, the change in total cost per book is +25. To find the initial cost of getting started before any books are printed, we look at the constant term in the equation, which is 1150. This means that the initial cost, or fixed cost, to publish the book (before printing any copies) is $1150.
