Final answer:
To calculate the simple interest on a PHP 15,000 deposit at a 5% interest rate over five years, you use the formula I = P × r × t, resulting in an interest of PHP 3,750.
Step-by-step explanation:
The question revolves around calculating the simple interest earned on a PHP 15,000 deposit with a 5% annual interest rate over a period of five years.
Simple interest can be calculated using the formula:
I = P × r × t
where I is the interest earned, P is the principal amount (initial deposit), r is the annual interest rate (as a decimal), and t is the time the money is deposited in years.
Using the formula, we can determine the interest as follows:
I = PHP 15,000 × 0.05 × 5
I = PHP 3,750
Therefore, the interest earned after five years is PHP 3,750.
