Question

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 randy are related by theequation 10x +1250 = y.Answer the questions below.Note that a change can be an increase or a decreaseFor an increase use a positive number. For a decrease use a negative numberwhat is the change in the total cost for each book printedwhat is te cost to get started before any books are printedsoCheckSave For LaterSubtAssetTe bere to search***SM

Answer 1

The equation desbribing the total cost is:

$y=10x+1250$

This equation has the form:

$y=mx+b$

where m is the slope and b is the y-intercept. Comparing both equations we conclude that in this case we have m=10 and b=1250.

The slope represents the change in cost for each book while the y-intercept represents the intial cost, therefore:

The change in the total cost for eah boog printed is 10.

The cost to get started before any books are printed is 1250.
