Hi! Since, we are using the exponential growth model in the problem, we would use the equation:

**A = P(1+r)^t**

In this case, "A" would represent the population in 1995. "P" would be the current population (5 billion), "r" would be the annual population increase rate (expressed as a decimal), and "t" would be the number of years passed from 1987 to 1995 (8 years).

Keeping all this in mind, let's plug in the values provided in the problem:

**Population = P(1+r)^t**

**Population = 5(1+0.02)^8**

**Population = 5(1.02)^8**

**Population in 1995 ~ 5.86 billion **
