Hi there First find the rate of growth between 1992 and 1998 The formula is P=Ae^rt P the population in 1998. (76 million) A the population in 1992 (72 million) E constant R rate of growth? T time 1,998−1,992=6 years We need to solve for r R=[log (p/A)÷log (e)]÷t R=(log(76÷72)÷log(e))÷6 R=0.009
Now find the population in 2012 P=Ae^rt P ? A 72 million R 0.009 T 2,012−1,992=20 years So P=72×e^(0.009×20) P=86.2 round your answer to get P=86 million
