well, we have our average total cost right here this is our average total cost at 48 cents that's the little green triangle here so it's 48 cents per unit times the total number of units our cost, the area in this rectangle so if I were to shade this in this little slightly smaller rectangle and so our profits are the difference between the two our total revenue is the area under the rectangle that has this marginal revenue line as its upper bound and our cost is the rectangle that has our average total cost this line right over here as its upper bound so our profits in this circumstance are going to be the area right over here the height is the difference between our marginal cost which is the same as our marginal revenue and our total cost so the heigh is going to be this two cents right over here we're taking the difference of 50 and 48 so it's gonna be 2 cents and then, the quantity produced is going to be 9000 units so 9000 we're making 2 cents per unit remember, our average cost our average total cost is 48 cents per unit we're selling that 50 cents per unit so we're making 2 cents per unit that's not 20 we're making 2 cents per unit 2 cents times 9000 units gives us that's 18000 cents, or 180 dollars of profit now what I want you to think about and we'll answer this in the next video is does it make sense to sell units at all and if so, how many units should we sell if, and here is the question if the market price is lower than your average total cost so does it make sense and how many units does it make sense to produce let's say if the market price were 45 cents per unit does it make sense for us to produce.

The marginal revenue function is below the inverse demand function at every positive quantity. The average marginal revenue received for each of these additional 20 units is $50/each. Marginal revenue is the income gained by selling one additional unit, while marginal cost is the expense incurred for selling that one unit. Marginal revenue refers to the money a company makes from each additional sale, while marginal cost is the amount it costs the company to produce extra units. The value P in the inverse demand function is the highest price that could be charged and still generate the quantity demanded Q. For example, if the demand function has the form He incurred the same cost, which leaves him with the same amount of profit on the boxes as well, which will add up to $2.50 ($0.50 x 5).
