Is the change in output compared to the change in total cost.

Marginal revenue, cost, and profit. Let $R(x), C(x),$ and $P(x)$ be, respectively, the revenue, cost, and profit, in dollars, Irom the production and sale of $x$ items. If $R(x)=5 x$ and $C(x)=0.001 x^{2}+1.2 x+60$ find each of the following. a) $P(x)$ b) $R(100), C(100),$ and $P(100)$ c) $R^{\prime}(x), C^{\prime}(x),$ and $P^{\prime}(x)$ d) $R^{\prime}(100), C^{\prime}(100),$ and $P^{\prime}(100)$ e) Describe in words the meaning of each quantity in parts (b) and (d).

Marginals and Differentials
Let $R(x)$ be the revenue and $C(x)$ be the cost from manufacturing $x$ items. Profit is defined as $P(x)=R(x)-C(x) .$ Show that at the value of $x$ that maximizes profit, marginal revenue equals marginal cost.
