Answer:

in half year

t = 1/2

Step-by-step explanation:

The formula for annual compound interest, including principal sum, is:

A = P (1 + r/n)^ (nt)

where A = amount after interest added (future value)

           p = principal amount

           r = annual interest rate = 12% = 12/100 =0.12

           n =number of time compounded  per year

           t = the number of years the money is invested or borrowed for

A = P (1 + r/n)^ (nt)

6773.76 = 5400(1+ 0.12/1) ^ 1/t

6773.76/5400 = (1+ 0.12) ^ 1/t

1.2544 = (1.12) ^ 1/t

log(1.2544) = log(1.12) ^ 1/t

log(1.2544) = 1/t log(1.12)

log(1.2544) / log(1.12) = 1/t

2 = 1/t

2t =1

t = 1/2
