Question 1089096

To produce a textbook, suppose a publisher spent $140,000 for typesetting and $6.50 per book for printing and binding.  The total cost to produce n books can be written as

C = 140,000 + 6.5n

Find the cost to produce one more textbook when you have already produced 10,000 textbooks.

Using the above equation, I have established that the total cost to produce 10,000 textbooks is $205,000, with the average cost being $20.50.  Not exactly sure how to work out the cost of "one more".
<pre>This is accounting, or maybe finance. You need to look in your textbook to determine how to calculate "ONE MORE" unit.
I did accounting, and if my memory serves me right, the correct calculation is below.
Don't quote me on this though, because as I said before, you need to consult your book. 

Cost to produce 10,000 textbooks: 140,000 + 6.5(10,000) = $205,000
Average cost to produce each book from the 10,000 batch: {{{matrix(1,3, "205,000"/"10,000", "=", "$20.50")}}}
Cost to produce "ONE ADDITIONAL" book: 140,000 + 6.5(1) = $140,006.50
Cost to produce 10,001 books: $205,000 + 140,006.50 = $345,006.50
Average cost to produce "ONE MORE", or a total of 10,001 books: {{{highlight_green(matrix(1,3, "345,006.5"/"10,001", "=", "$34.50"))}}}
Now, you need to check your textbook and see if I'm right!
