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.

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.
