Question

The population of Indonesia was 191,256,000 in 1990 and was growing at a rate of 1.9% per year. Write an equation to model the population every year.

Answer 1

0.019x+191,256,000

My Work/Reasoning:
Say that the year is "1990+x".
Every year the population grows by 1.9%. 1.9%(1990+x)
The population was 191,256,000 in 1990. 1.9%x+191,256,000
The percentage symbol means "out of a hundred". 0.019x+191,256,000
