Here,
A is the final worth of the investment
P denotes the Principal amount of money that is invested
r denotes the rate of the compound interest
t denotes the time period in years
n denotes the number of times interest is compounded in one year
Given Information
P = $8,000
r = 6% = 0.06
n = 4 (∵ Compounded quarterly)
t = 10 years
Solving for A
Substituting the values of P, r, n, and t in the above mentioned formula of compound interest, we get,
Rounding the answer to two decimal places, we get,
Therefore, Nazerhy would get $14,512.15 after 10 years.
