Why is cell division important for unicellular and multicellular organisms

Multicellular organisms need cell division to grow and to replace dead or damaged cells and unicellular cell division is the only way single-celled organisms can reproduce. It means the same as cells died.

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.
