Q5. In 1990, the population of a country was estimated at 4 million. For any subsequent year the population, P(t) (in millions), can be modeled by the equation P(t) = 240/(5 + 54.99e-0.0208t), where t is the number of years since 1990. Estimate the year when the population will be 21 million.a. approximately the year 2093b. approximately the year 2041c. approximately the year 2088d. approximately the year 2016
