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 y=1150+25x
Answer the question 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)?
The change in the total cost for each book printed can be found by looking at the coefficient of x in the equation. In this case, the coefficient is 25. Therefore, for each book printed, there is a increase in cost of $25.
The cost to get started (before any books are printed) can be found by looking at the constant term in the equation. In this case, the constant term is 1150. Therefore, the cost to get started is $1150.
