Answer:

8.7 so either 8 or 9 tenth of a year

Step-by-step explanation:

Is it compounded per month? I assume

1. Compound interest formula

FV = PV(1+r/100k)^kn

FV is the future value,

PV is the present value,

n is the number of years,

k is the number of compounding periods per year

r% is the nominal annual rate of interest

2. Plug in numbers

3550 = 2400(1+4.6/100*12)^12*n

71/48 = (6023/6000)^12n

12n = logBase(6023/6000)*(71/48)

n = answer/12

n ≈ 8.70
8.7 so 8 or 8 of they year is the amount.
