In the year 2012, the population of India was about 1.22 billion. The exponential function P(t)=1.22(1.021)^t is used to calculate the India's population t years from the year 2012. Estimate the population t year of India in the 2020. Can someone help me break down this problem thanks

same as the coffee  plug in the value for t
P(20202012) = P(8) = 1.22(1.021)^8 = 1.22*1.18 = 1.44 billion
