flows directly into the indian ocean
rises to the surface and flows to the equator
passes the equator and flows toward antarctica
splits into three different currents

The answer is C, passes the equator and flows toward Antarctica

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.
