Question

A populations growth rate is r=3% per year how many years does it need to reach ten times its initial size

Answer 1

333.3 years

Explanation:

The formula

• I = Prt

Condition

• I needs to equal 10 x P

Solving

• I = Prt
• 10P = Prt
• 10 = 0.03 x t
• t = 10/0.03
• t = 10/3 x 100 = 1000/3 = 333.3 years
