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.

A plastic is any material that can be shaped or molded into any form -- some are naturally occurring, but most are man-made.Plastics are made from oil.Oil is a carbon-rich raw material, and plastics are large carbon-containing compounds. They're large molecules called polymers, which are composed of repeating units of shorter carbon-containing compounds called monomers.lastics are everywhere.
