Answer:
16 cents
Explanation:
A = P (1 + r)n
A = $1 (1 + 0.05)3
A = $1 x 1.16
A = $1.16
To find the compound interest only;
Compound Interest = Final Value - Initial Value
Compound Interest = $1.16 - $1
Compound Interest = $0.16
Hence the compound interest John will earn in his savings account will be 16 cents.
