$1400 bonus
5 year CD investment
interest rate = 1.47%
compounded annually
Compound interest formula:
A = P (1 + r/n)^ nt
Where:
• A = future value
,
• P= principal = 1400
,
• r= interest rate = 1.47 % = 1.47 / 100 = 0.0147 (decimal form)
,
• n= compounding periods = 1
,
• t = years = 5
Replacing:
A = 1400 ( 1 + 0.0147)^5
A = $ 1,505.970059 = $ 1,505.97
Answers:
(a) = $ 1,505.97
(b) = 1,505.970059 - 1400 = $105.97
