Question

The population of Winnemucca Nevada can be modeled by P=6191(1.04)^t where t is the number of years since 1990. What was the population in 1990? By what percent did the population increase by each year?
To be honest, this question is very simple. You can look at the number after the decimal in (1.04) to find the percentage. just multiply the .04 by 100 to find the percentage.

As for the population in 1990, since the year is 1990, t would be equal to 0, (no years since 1990 from 1990)

P= 6191 (1.04)^0
P=?
6438.64
No, anything with a power of 0 is 1.
