Q The cost of producing x widgets is given by the following cost function:\r\n\r\n![\"image2.png\"](\"https://www.dummies.com/wp-content/uploads/202625.image2.png\")
\r\n\r\nDetermine the marginal cost, marginal revenue, and marginal profit at x = 100 widgets.\r\n
Marginal cost
\r\nMarginal cost is the derivative of the cost function, so take the derivative and evaluate it at x = 100.\r\n\r\n![\"image3.png\"](\"https://www.dummies.com/wp-content/uploads/202626.image3.png\")
\r\n\r\nThus, the marginal cost at x = 100 is $15 this is the approximate cost of producing the 101st widget.\r\nMarginal revenue
\r\nRevenue, R(x), equals the number of items sold, x, times the price, p:\r\n\r\n![\"image4.png\"](\"https://www.dummies.com/wp-content/uploads/202627.image4.png\")
\r\n\r\nMarginal revenue is the derivative of the revenue function, so take the derivative of R(x) and evaluate it at x = 100:\r\n\r\n![\"image5.png\"](\"https://www.dummies.com/wp-content/uploads/202628.image5.png\")
\r\n\r\nThus, the approximate revenue from selling the 101st widget is $50.\r\nMarginal profit
