How can I calculate for quantity when I know the price and MC? Price = 42.00 and MC = .006

To calculate the quantity when you know the price and marginal cost (MC), you need to use the formula for profit maximization in economics. The profit (π) is equal to the difference between revenue (R) and the cost (C), which can be expressed as:

π = R - C

Revenue is the product of price (P) and quantity (Q):

R = P * Q

The cost can be calculated as:

C = MC * Q

To find the quantity (Q), we can rearrange the profit equation:

π = P * Q - MC * Q

Since we know the price (P) and marginal cost (MC), we can substitute them into the equation:

π = 42.00 * Q - 0.006 * Q

Simplifying further:

π = (42.00 - 0.006) * Q

Now, to find the quantity (Q), divide both sides of the equation by (42.00 - 0.006):

Q = π / (42.00 - 0.006)

Keep in mind that in order to calculate the quantity accurately, you need to have information about the profit (π) as well. With the given price and marginal cost, you can calculate the quantity once you have the profit value.
