Scientists find the fossilized remains of a fish in the middle rock layers of a research site. They find the fossil of an insect in the lowest rock layers. What can be concluded from this evidence?

A. the insect lived before the fish

B. the insect lived on the bottom of the ocean that the fish lived in

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.

i'm guessing this is from edg enuity so the answers would be, from top to bottom,
