KIM [24]

Answer:

831.1 million

Step-by-step explanation:

If the exponential model describes the population after 2003 and we must determine the population of the country in 2003 then t=0 because the time only starts after 2003:

$A=831.1\cdot{e^(0.022\cdot{0})}$

e to the power of 0 is equal to 1:

$A=831.1\cdot{e^(0.022\cdot{0})}=831.1\cdot{1}=831.1$

The population in 2003 is 831.1 million
