Answer:
The annual increase in the percentage of a pollution can be determined by some mathematical calculation.
Step-by-step explanation:
- In order to determine the annual percentage increase over one year for a city population, we must do the following,
- First we must subtract starting value that is the initial population of the city at the starting of the year from the final value that is the final population of the city at the end of the year.
- Now divide the whole by the starting value.
- This gives you the value of increase in the rate of growth, Now inorder to obtain it in percentage format, we must multiply the resultant value by 100.
This finally gives you the rate of increase in the population in percentage.

Answer:
YES, the equipment should be purchased
Step-by-step explanation:
You borrow $10000 for the piece of laboratory and the cost of money is 12%. After 3 years you will need to pay the $10000 you borrowed and the extra amount caused by the interest. 12% of $10000 if $1200, so you will end up having to pay $10000+$1200 = $11200. In three years your equipment saves you $4000*3 = $12000, which is bigger than the amount you have to pay. So, in the end the equipment should be purchased because it gives you a gain of $800.
