The Solution:

Given:

Lella deposited $600 into an account that pays 2% simple interest per year.

Required:

To find the interest Lella will get in the first 3 years.

To find the interest, we shall use the formula below:

[tex]I=\frac{PRT}{100}[/tex]

In this case,

[tex]\begin{gathered} P=\text{amount deposited=\$600} \\ T=\text{time in years =3 years} \\ R=\text{rate in percent=2\%} \\ I=\text{simple interest paid=?} \end{gathered}[/tex]

Substituting these values in the above formula, we get

[tex]I=\frac{600\times2\times3}{100}=6\times2\times3=\text{ \$36}[/tex]

Thus, the interest she will be paid in 3 years is $36.00

Therefore, the correct answer is $36.00
