Question

hey guys please solve this it's urgent

Answer 1

let population initially be x

Net increase = 4 - 1/2 = 7/2% = 3.5%

population after 1 year = 103.5% of x

population after 2 year = 103.5% of 103.5% of x

= 1.071 x

population after 3 years = 103.5% of 1.071 x

= 1.108 X

net increase = x( 1.108 - 1) = 0.108 x

% increase = 10.8%
