Explanation:

Given information

The modeled function given is y = 1200 + 10x

Where,

y represents the total cost of publishing a book

x represents the number of copies of the book

Part a

What is the change in the total cost for each book printed?

Remember that the change in the total cost for each book printed is the same thing as the slope

The next step is to find the slope

Recall that, the slope-intercept form is given as

y = mx + b

where m is the slope of the line

b is the intercept of the line

From the equation given

y = 10x + 1200

Hence, the slope is 10 dollars/ copy

Therefore, the change in total cost for each book printed is 10 dollars/copy

Part B

What is the cost to get started?

The cost to get started can be calculated when no book has been printed

This implies that x = 0

Therefore

y = 1200 + 10(0)

y = 1200 + 0

y = $ 1200

Therefore, the cost to get started is $1200
