9.9 yearsstep-by-step explanation:
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.
