As given, Amount or A = 250
Time period = 12 years or n=12
Interest = 6% or i=0.06
Value of the investment = [tex]A[((1+i)^{n}-1)/i][/tex]
= [tex]250[((1+0.06)^{12}-1)/0.06][/tex]
= [tex]250[((1.06)^{12}-1)/0.06][/tex]
= [tex]250[(2.0121-1)/0.06][/tex]
= [tex]250(16.869)[/tex] = 4217.25 which is near to $4217.48
Hence, option C = $4217.48 is the answer.
