Unfortunately, a 100 pound weight loss is usually always accompanied by loose skin. This may involve the face, arms, breasts, upper back, lower back, abdomen, buttocks and thighs. The degree of sag is dependent upon several factors including the patient's skin elasticity and the magnitude of the weight loss.
Here are total cost formulas, average variable, marginal cost, and more, (work out your own algebra to find alternatives): Average Total Cost (ATC) = Total Cost / Q (Output is quantity produced or âQâ).Average Variable Cost (AVC) = Total Variable Cost / QAverage Fixed Cost (AFC) = ATC â AVC.ere are total cost formulas, average variable, marginal cost, and more, (work out your own algebra to find alternatives): Average Total Cost (ATC) = Total Cost / Q (Output is quantity produced or âQâ).
Tips. 1  Long-run marginal costs differ from short-run in that no costs are fixed in the long run. 2  The general formula for calculating short-run marginal cost is: MC= d(TC)/d(Q) where TC is total cost, Q is quantity, and d signifies the change in these values.tep 3. Calculate the change in total cost when producing a given quantity of additional units. Total cost is equal to fixed costs plus variable costs. The change in total cost will be the new total cost after producing any additional units, minus the total cost before producing the units.
