The fixed component in this example is $3,000 per month. The variable cost component is $10 per unit of output. Hence, at a production level of 500 units, the total electric cost is $8,000 [$3,000 + ($10 x 500)].
Plastics are derived from organic products. The materials used in the production of plastics are natural products such as cellulose, coal, natural gas, salt and, of course, crude oil. Crude oil is a complex mixture of thousands of compounds. To become useful, it must be processed.he materials used in the production of plastics are natural products such as cellulose, coal, natural gas, salt and, of course, crude oil.

PVC (polyvinylchloride) is generally seen as a har â¦ d plastic. It is made from vinyl chloride monomers which are pieced together to form a long chain. These are then placed alongside each other to form a coherent strand. This strand can be made into almost any shape with the use of heat and pressure.lastic resins are, in turn, used to produce many different types of plastic. The majority of what we know as plastic today is made from materials that are extracted from crude oil. Often the same type of crude oil that is used to produce the fuels for cars.
