Let the number of extra pages be denoted by 'x'.
Also Let the Total cost be denoted by 'y'.
Now we can say that;
Total cost will be equal to sum of Service charge to make a photo book and Cost per extra page multiplied by number of extra pages and Cost to ship the complete photo book.
framing in equation form we get;
Hence the expression to determine the total cost in dollars is .
Answer:

Then we can use one of the given points to find the y-intercept. Since the only complete one is (12,10), we'll use that.
So now we have .
Now we can use our other point with the missing y-value and solve for y.
So the missing value is 64.
Hope this helps!
