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.
Product Summary. A plastic tack is a kind of tack made of the material of plastic which is a material of a wide range of synthetic or semi-synthetic organic solids used in the manufacture of industrial products. Plastics are typically polymers of high molecular mass, and may contain other substances to improve performance and/or reduce production costs.
Many plastic toys are made of polyvinyl chloride (aka PVC or vinyl), a type of plastic that is made with phthalates. Phthalates leach out of various products and into our blood streams, and are implicated in reproductive disorders and respiratory problems. Theyâre also found in some pacifiers, teethers and chew toys.
