Help please! ;-; I have no idea how to do this.
Scenario 1: [DO NOT ANSWER SCENARIO 1, BUT use the information in Scenario 1 to solve the other two scenarios.]
The population of a country is initially 2 million people and is increasing at 4% per year. The country’s annual food supply is initially adequate for 4 million people and is increasing at a constant rate adequate for an additional 0.5 million people per year. Based on these assumptions, in approximately what year will this country first experience shortages of food? Explain how you arrived at this answer in complete sentences.
Scenario 2:
If the country doubled its initial food supply and maintained a constant rate of increase in the supply adequate for an additional 0.5 million people per year, would shortages still occur? In approximately which year? Explain how you arrived at this answer in complete sentences.
Scenario 3:
If the country doubled the rate at which its food supply increases, in addition to doubling its initial food supply, would shortages still occur? In approximately which year? Explain how you arrived at this answer in complete sentences.
