Step-by-step explanation:

Initial amount deposited into the account is $18,000 This means that the principal is

P = 18000

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 4%. So

r = 4/100 = 0.04

It was compounded for just 18 years. So

t = 18

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 = 18000 (1+0.04/4) ^4 * 18

A = 18000 (1.01) ^72 = $36847.79
