Question 2 1 pts If the demand for a certain product is given by p = 300 - 20g, where q Is the quantity demanded by the market when the price per unit of the Product is for p dollars. Calculate the marginal income, when 12 units are sold

To calculate the marginal income when 12 units are sold, we need to find the derivative of the demand function with respect to quantity (g) and then evaluate it at g = 12. The demand function is given by: p = 300 - 20g To find the marginal income, we differentiate the demand function with respect to quantity (g): dp/dg = -20 The derivative of the demand function with respect to quantity is -20. This represents the rate of change of price with respect to quantity. To calculate the marginal income when 12 units are sold, we substitute g = 12 into the derivative: dp/dg |g=12 = -20 Therefore, the marginal income when 12 units are sold is -20.This means that for each additional unit sold beyond the 12th unit, the income decreases by $20.
