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 25x+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? What is the cost to get started(before any books are printed)?

Answer :

the change is positive 25 dollars for printing each book, the cost to get started is 1150 dollars. 

Answer:

Step-by-step explanation:

Given that y represent the total cost of publishing a book (in dollars) and x represent the number of copies of the book printed.

X and Y have a linear relation as

[tex]y =25x+1150[/tex]

We find that slope of the line is 25

i.e. for one increase in x there is 25 dollars increase in y because slope is positive 25

1150 is the cost even if no copy is printed.  This is the fixed cost.

a) The  change in the total cost for each book printed is 25 dollars

b) the cost to get started(before any books are printed) is 1150 dollars
