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.

Making a plastic from potato starch â. making the plastic. In this activity you will make a plastic film from potato starch and test its properties. Potato starch is a polymer made of long chains of glucose units joined together. It actually. contains two polymers: â Amylose, which is a straight chain of glucose units. â Amylopectin, which is a branched polymer, also made of glucose units. The amylopectin prevents the starch from becoming plastic-like.
