Answer:

Hence correct choice is B. 58,381

Explanation:

Given equation is
y=18000(1.04)^x.

There x represents number of years. We need to find about which is the best prediction for the population in year 30.

To find that we will plug x=30 into above formula and simplify


y=18000(1.04)^x


y=18000(1.04)^(30)


y=18000(3.24339751003)


y=58381.1551805

Which is approx 58381

Hence correct choice is B. 58,381.
