how do you calculate the profit maximizing quantity

To calculate the profit-maximizing quantity, you need to determine the quantity at which the marginal revenue (MR) equals the marginal cost (MC).

The steps to calculate the profit-maximizing quantity are as follows:

1. Calculate the marginal revenue (MR), which is the change in total revenue resulting from selling one additional unit. This can be calculated by dividing the change in total revenue by the change in quantity.

2. Calculate the marginal cost (MC), which is the change in total cost resulting from producing one additional unit. This can be calculated by dividing the change in total cost by the change in quantity.

3. Set MR equal to MC and solve for the quantity. MR = MC is the condition for profit maximization.

Mathematically, MR = MC can be represented as:
MR = MC.

Once you have solved for the quantity when MR = MC, you have found the profit-maximizing quantity.
