Given:
The total cost (in dollars) of producing x college algebra books is C (x) = 42.5x + 80,000.
Explanation:
The given cost function is a linear cost function of the form C (x) = mx + b,
Where b represents the fixed cost, x is the number of items and m represents the marginal cost.
So on comparison with the generalized cost function, the marginal cost is $$\42.50$$.
