Answer: 209.7152
Step-by-step explanation: You take your number, 20, and do it plus itself times .6. It would end up looking like this: 20+20*.6=32 32+32*.6=51.2 ... until you get to 5 times which is 209.7152
Solution here,
initial population=20
By the question, thepopulation increases by 60% in 1 year.
i.e. after 1 year population will be 20+60% of 20
=20+(60/100)×20=20+0.6×20=20+12=32
Now,
after 2 years population will be 32+60% of 32=51.2
after 3 years population will be 51.2+60% of 51.2
=81.92
after 4 years population will be 81.92+60% of 81.92
=131.072
after 5 years population will be 131.072+60%of131.072=209.7152
