Principal Amount x Interest Rate

Jennifer Herrera · Answer 2

yearlyInterest = principalAmount * interestRate * year

Step-by-step explanation:

The general formula for interest is given as:

(principal * rate * time) / 100

but in this case the rate has been converted to decimal and the time is in year.

The principal is represented as principalAmount

The rate is represented as interestRate

The time is represented as year

So, the arithmetic expression is to multiply every term together without dividing by 100 since rate is expressed as a decimal fraction.
