The government has recently introduced a marketable permit program for major polluters where one permit gives permission to pollute one unit. When the program is introduced, Firm A emits 800 units of pollutant and so is granted 800 permits. After one year, firms are issued 10% fewer pollution permits. If Firm A reduces its pollutants from 800 units to 690 units, how many permits does it sell after one year

Firm A can sell 30 permits as it has an excess of 30 permits.

Explanation:

As the permits are reduced by 10%, then the permits issued to Firm A after one year will be,

Permits issued - After one year = 800 * (1 - 10%) = 720 permits

Now as Firm A has reduced its pollutant units to 690 units, which is more than the permits issued to it, it has an excess of 30 permits.

Excess = 720 - 690 = 30 permits

Firm A can sell these permits after one year.

1) the stages a new product goes through from beginning to end, i.e., the stages that a product passes through from introduction through growth, maturity, and decline. 2) the time from initial research and development to the time at which sales and support of the product to customers are withdrawn. 3) the period of time during which a product can be produced and marketed profitably.
