Please Can you help and advise with this

a. In 2000, the population of a country was approximately 6.35 million and by 2069 it is projected to grow to 12 million. Use the exponential growth model A = Apekt, in which t is the number of years after 2000 and A, is in millions, to find an exponential growth function that models the data. Projected b. By which year will the population be 15 million? Year a. The exponential growth function that models the data is A = (Simplify your answer. Use integers or decimals for any numbers in the expression. Round to two decimal places as needed.)
