How domplants reproduce?

It doesn't matter what plant/flower it is:

A flower can either have the male or female part or both the parts. Flowers in plants carry out the reproductive functions in plants when both the male and female gametes are fused to produce the seeds which bear the fruit. These seeds germinate to produce new plant structures.

Explanation:

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.
