Answer and Explanation:
Future value = Present value x (1+i)^n, where
n = number of years
I = interest rate
From the question n = 8 years for the amount $400 ,
n= 7years for $250 ,
n=4years for $300
interest = 3%= 0.03
Future value of $400 = 400 (1 + 0.03)^8 = $506.71
Future value of $ 250 = 250 (1+0.03)^7 = $307.47
Future value of $ 300 =300(1+0.03)^4 = $337.65
