Step-by-step explanation:

The current global population is growing at an annual rate of 1.35 percent. The growth rate is exponential. We would apply the formula for exponential growth which is expressed as

A = P (1 + r) ^t

Where

A represents the population after t years.

t represents the number of years.

P represents the initial population.

r represents rate of growth.

From the information given,

P = 6.1 * 10^9

r = 1.35% = 1.35/100 = 0.0135

t = 1

Therefore

A = 6.1 * 10^9 (1 + 0.0135) ^1

A = 6.1 * 10^9 (1.0135) ^1

A = 6182350000

The number of people that would be added is

6182350000 - 6100000000

= 82350000
