What is the supply scale and how does it differ from the demand scale?

In economics, the supply scale is a measure of how many goods, with varying prices, sellers can supply to buyers. The supply increases in proportion to the cost of the products sold. The scale of demand, in turn, is a table with a curve illustrating the capabilities of the consumer, and, as a consequence, his willingness to pay the specified amount for certain items of sale. Comparison of these data gives a clear picture of the market situation in society, helping to regulate and balance trade relations.
