how much interest will Tamara earn on her investment at the end of 3 years?

Given:
Principal amount, P = $15000
Interest rate, R = 4%
Time, T = 3 years
To find the interest Tamara will earn on her investment, use the simple interest formula below:
[tex]\text{Interest = }\frac{P\times R\times T}{100}[/tex]Thus, we have:
[tex]\begin{gathered} \text{Interest = }\frac{15000\times4\times3}{100} \\ \\ \text{Interest = }\frac{180000}{100} \\ \\ \text{Interest = 1800} \end{gathered}[/tex]Therefore, Tamara will earn an interest of $1,800 at the end of 3 years
ANSWER:
B. $1,800
