Find how much interests $15000 earns in 2 years in a certificate of deposit paying 7.5% interest compounded quarterly the interests earned in 2 years is

Step-by-step explanation:

Initial amount deposited in the certificate of deposit is $15000 This means that the principal so

P = 15000

It was compounded quarterly. This means that it was compounded 4 times in a year. So

n = 4

The rate at which the principal was compounded is 7.5%. So

r = 7.5/100 = 0.075

It was compounded for 2 years. So

t = 2

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 = 15000 (1+0.075/4) ^4*2

A = 15000 (1.01875) ^8 = $17403

The interest would be

17403 - 15000 = $2403
