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 \( 10 x+1150=y \). Answer the questions below. Note that a change can be an increase or a decrease. For an increase, use a positive number. For a decrease, use a negative number. What is the change in the total cost for each book printed?

Each additional book printed increases the total cost by $10. This is derived from the term \( 10x \) in the equation \( 10x + 1150 = y \), where \( 10 \) represents the variable cost per book. So, every time you print one more copy, you incur an additional cost of $10.

An animal breeder can buy four types of food for Vietnamese pot-bellied pigs. Each case of Brand A contains 25 units of fiber, 40 units of protein, and 40 units of fat. Each case of Brand B contains 100 units of fiber, 130 units of protein, and 110 units of fat. Each case of Brand C contains 275 units of fiber, 350 units of protein, and 310 units of fat. Each case of Brand D contains 200 units of fiber, 260 units of protein, and 200 units of fat. How many cases of each brand should the breeder mix together to obtain a food that provides 3975 units of fiber, 5100 units of protein, and 4440 units of fat? cases of Brand D. There are four ways in which the breeder can mix brands to obtain a food that provides 3975 units of fiber, 5100 units of protein, and 4440 units of fat. If \( w=0 \), the solution is \( (0,15,9,0) \). If \( w=1 \), the solution is \( (1,10,10,1) \). If \( w=2 \), the solution is \( (2,5,11,2) \).
