Hence, at a production level of 500 units, the total electric cost is $8,000 [$3,000 + ($10 x 500)]. The mixed cost illustrated in the above chart is called a step function. An example of such cost behavior would be the total salary expense for shift supervisors.

3. Color the sticky tack. Take a marker (preferably blue, the color of real sticky tack) and color the sticky tack. Any type of marker or ink will do. Add a few drops of color, then roll and stretch the glue ball to mix the color in.. Roll and stretch the glue. Place it between your palms and roll it around, smoosh it, and form it into a ball, then stretch it out.
