Given:
The given equation is 1200 + 10x = y
where x is the number of xopies of book printed and y is the total cost of publishing the book .
b) To obtain the cost to get started;
Substitute x = 0 into the given equation.
1200 + 10(0) = y
1200 = y
Hence, the cost to get started is $1200
a) To find the cost for each book;
Put x =1 in the given equation.
1200 + 10(1) = y
1210 =y
Change in cost for each book printed is 1210 - 1200 = 10
Hence, the change in the total cost for each book printed is $10.
