Many enzymes are named for the substrate on which they work, either to build or disassemble molecules. also, enzyme names often end in “-ase.” for example, lactase is the enzyme that breaks down lactose. with a name like “telomerase,” we can deduce that telomerase is probably

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.
