Two tiny holes called the Eustachian tubes. These connect their ears (tympanic membranes) to their mouth. In males, 2 holes are in the vocal sac. In the back of the mouth are 2 holes: the glotiss and the gullet.
Private practice rates. If you are working in a supervised private practice, on the other hand, you will likely make more per hour. For example, as an LPC intern, I had a sliding scale that ranged from $30 to $75 per session. I have also seen interns charge $10 per session and more than $100 per session. Please remember that published rates, even on a sliding scale, does not mean that people are pulling those fees in at all, or with every client.
Definition. The Average Variable Cost (AVC) is the total variable cost per unit of output. This is found by dividing Total Variable Cost (TVC) by total output (Q). Total Variable Cost (TVC) is all the costs that vary with output, such as materials and labor.ummary. The average variable cost is a firm's variable cost per unit of output. Most AVC functions will start decreasing and then at one point, begin to increase. A firm will chose to shut down production in the short run if the market price is less than the average variable cost of production.
