Explanation Given: The currently number of rats is 200, monthly growth rate is 8 % and time = 1 year. Concept Used: Exponential Growth: A quantity that grows by the same percent at regular time periods is said to have exponential growth. There are many real − life examples of exponential growth, such as population, bacteria, viruses, and radioactive substances, just to name a few. Modelling Exponential Growth: Exponential Growth: y = C ( 1 + r ) x C − Initial amount; x − numbers of time intervals in month, ( 1 + r ) is growth factor; r is growth rate (often a percent) Calculation: Modelling Exponential Growth: Exponential Growth: y = C ( 1 + r ) x C − Initial amount; x − numbers of time intervals in month, ( 1 + r ) is growth factor; r is growth rate (often a percent) Here: C = 200; r = 8% and x = 1 year = 12 month y = C ( 1 + r ) x C
