Marginal cost is the cost of increasing the quantity produced (or purchased) by one unit. If the fixed cost for n products is $10,000 and the marginal cost is $250, and the total cost is $16,000, what is the value of n?  Choose one:
A) 10 B) 24 C) 60 D) 70 E) 85
Total cost for n products = fixed cost for n products + n*marginal cost --&gt; $16,000 = $10,000 + n * $250 --&gt; n = 24.   Answer: 24.
