Sophie have earned more interest after 5 years.

And, Sophie have earned $100.12 more interest than Adam.

What is Simple interest?

A quick and easy method of calculating the interest charge on a loan is called a Simple interest.

Given that;

Sophie put $3330 in a savings account at a simple interest rate of 7.4% per year.

And, Adam put $2795 in a savings account at a simple interest rate of 8.1% per year.

Now,

Find the simple interest as;

For Sophie;

Interest = PRT

            = $3,330 x 7.4% x 5

            = $3,330 x 0.074 x 5

            = $1,232.1

For Adam;

Interest = PRT

            = $2,795 x 8.1% x 5

            = $2,795 x 0.081 x 5

            = $1,131.97

Thus, Sophie have earned more interest after 5 years.

And, The amount = 1232.1 - 1131.97

                            = $100.12

Therefore, Sophie have earned more interest after 5 years.

And, Sophie have earned $100.12 more interest than Adam.
