Question

The world population in 1993 is projected to be billion people.

Answer 1

Step-by-step explanation

The growth model is given by the following expression:

`A=A_0(1+r)^t`

Where A_0=Initial Population = 5 billion

r=growth rate = 2% = 0.02 in decimal form

t=time = 1993 - 1987 = 6 years

Plugging in the numbers into the equation:

`A=5(1+0.02)^6`

Computing the power:

`A=5\cdot(1.02)^6`

Computing the product:

`A=5\cdot1.13`

Multiplying numbers:

`A=5.63billion`

In conclusion, the population in 6 years will be of 5.63 billion.
