Predict what changes in the reef ecosystem might occur if coral continue to decline.

Without reefs, billions of sea life species would suffer, millions of people would lose their most significant food source, and economies would take a major hit. But it's not just about the jobs.

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.

true is the final answer!
