Why do young barn owls need feathers

The owls feathers are very soft, the flight

feathers are covered in a thin hair- like

structure that traps air within the feather

surface. They generally avoid hunting in rain

as wet feathers increase noise and

reduce efficiency.

Explanation:

young barn owls need feathers to keep them warm

9.9 years

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
