Question

0.015x4 + x – 3, where x represents the number of car sold. What is the profit at x = 100

Answer 1

Answer:

Marginal Profit = 100 .

We are given with the Profit function for a car, P(x) = 500 -  - 100

Here, x = number of units sold

Now, Marginal function is given by first derivative of Original Function which is Profit function;

So, First derivative of Profit Function, P(x)' = 500 * (1) - 2* - 0

       {because derivative of constant is zero}

So, Marginal Function, M(x) = 500 - 2 *

Hence, marginal profit if 200 units are sold = 500 - 2 * 200 = 500 - 400 = 100 .
