The population of a country is currently at 56 million and is forecast to rise by 3.7% each year. It is capable of producing 2500 million units of food each year, and it is estimated that each member of
the population requires a minimum of 65 units of food each year. At the moment, the extra food
needed to satisfy this requirement is imported, but the government decides to increase food produc-
tion at a constant rate each year, with the aim of making the country self-sufficient after 10 years.
