Answer:the total value of the account after 3 years is $7266
Step-by-step explanation:
Initial amount that Ryan invested into account is $500 This means that the principal is P, so
P = 7000
It was compounded annually. This means that it was compounded once in a year. So
n = 1
The rate at which the principal was compounded is 1.25%. So
r = 1.25/100 = 0.0125
It was compounded for 3 years. So
n = =3
The formula for compound interest is
A = P(1+r/n)^nt
A = total amount in the account at the end of t years. Therefore
A = 7000 (1+0.0125/1)^1×3
A = 7000(1.0125 )^3= $7266
N=1 4+7n=71 that is the answer
