You have loaned a friend $100 and will charge him 5% annua simple interest when he pays it back.
kotykmax [81]

The annual interest would be $5 if you have loaned a friend $100 and will charge him 5% annually and the total amount would be $105.

<h3>What is simple interest?</h3>

It is defined as the interest based on the principal amount, it does not include the compounded amount. The interest calculates on the initial amount of borrowed amount.

We have:

You have loaned a friend $100 and will charge him 5% annually.

As we know:

A = P(1 + rt)

P = $100

r = 5% = 0.05

t = 1 years

A = 100(1 + 0.05×1)

A = $105

I = A - P = 105 - 100 = $5

Thus, the annual interest would be $5 if you have loaned a friend $100 and will charge him 5% annually and the total amount would be $105.
