Determine the monthly profit when the company sells 500 mugs?

To determine the monthly profit when the company sells 500 mugs, we need to calculate the total revenue and total cost.

Let's assume the company sells each mug for $10.

Total revenue = 500 mugs * $10/mug = $5000

Now, let's calculate the total cost. Let's assume the cost to produce each mug is $5.

Total cost = 500 mugs * $5/mug = $2500

Monthly profit = Total revenue - Total cost
Monthly profit = $5000 - $2500
Monthly profit = $2500

Therefore, the monthly profit when the company sells 500 mugs is $2500.

The provided context does not mention anything about the costs associated with producing and selling the mugs, so I cannot calculate the profit.
