#### Explanation:

The money earned in simple interest is given by the equation:

${S}_{f} = {S}_{i} \cdot r \cdot n$

where:

• ${S}_{i} , {S}_{f}$ are the initial and final amount of money

• $r$ is the interest rate

• $n$ is the number of years

We got: $n = 6 \setminus \text{months} = 0.5$.

So, we earn:

S_f=$22000*1.5%*0.5 =$11000*0.015

=\$165
