Answer: $342

Step-by-step explanation:

Formula : Simple interest = Principal amount  x  time  x  rate

Given:   Principal amount = $1,200

r= 1.5% = 0.015  [divide percentage by 100 to remove %]

t= 18 years

Simple interest = 1200 (18)(0.015) = $324

Hence, the interest earned in the account after 18 years = $342
