Cameron has decided to diversify his investment in the following way: how much total interest will Cameron earn on his investment at the end of 3 years?

The total interest that will Cameron earn will be equivalent to the multiplication of his total account, the interest. rate, and total years of his investment

For example:

if Cameron has $3,000 in account earning with 2.7 % simple interest rate,

at the end of 3 years, his total interest would be:

3 x 2.7 % x $ 3,000 = $243
