Final answer:
The value of the investment after 4 years is Php 1800.
Step-by-step explanation:
To calculate the value of an investment after a certain period of time with simple interest, you use the formula:
Total Value = Principal + (Principal * Interest Rate * Time)
Using the given information, we can substitute the values into the formula:
Total Value = Php 1500 + (Php 1500 * 0.05 * 4)
Total Value = Php 1500 + Php 300
Total Value = Php 1800
Therefore, the value of the investment after 4 years is Php 1800.
