Which of the following is a way to calculate the marginal cost of the \[100^{\text{th}}\] unit of output? Choose 1 answer: Choose 1 answer: (Choice A) \[\dfrac{\text{Fixed costs of producing }100\text{ units}}{100}\] A \[\dfrac{\text{Fixed costs of producing }100\text{ units}}{100}\] (Choice B) \[\dfrac{\text{Variable costs of producing }100\text{ units}}{100}\] B \[\dfrac{\text{Variable costs of producing }100\text{ units}}{100}\] (Choice C) \[\text{Total cost of producing } 100 \text{ units} - \text{Total cost of producing }99\text{ units}\] C \[\text{Total cost of producing } 100 \text{ units} - \text{Total cost of producing }99\text{ units}\] (Choice D) \[\text{Fixed costs} + \text{Variable cost of producing }100\text{ units}\] D \[\text{Fixed costs} + \text{Variable cost of producing }100\text{ units}\] (Choice E) \[\dfrac{\text{Fixed costs of producing } 100\text{ units} + \text{Variable costs of producing } 100\text{ units}}{100}\] E \[\dfrac{\text{Fixed costs of producing } 100\text{ units} + \text{Variable costs of producing } 100\text{ units}}{100}\]
