Answer:
(b) The percentage growth rate is constant
377 million in 2035
Step-by-step explanation:
Perhaps the defining characteristic of an exponential function is that its rate of change is proportional to its value. When the population growth rate is expressed as a constant percentage of the population, that is saying the growth is exponential.
A growth rate of 0.8% per year means the population is multiplied by 1+0.8% = 1.008 each year. After 19 years, it is multiplied by 1.008^19.
The population in 2035 is projected to be ...
324 × 1.008^19 ≈ 376.96 ≈ 377 . . . million people
