Let x be the amount that Dylan invested at 8% and y be the amount that he invested at 10%.

We know that:

• x + y = P 120,000 (the total amount invested is P 120,000)

• 0.08x = 4(0.10y) (the interest earned at 8% is four times the interest earned at 10%)

Simplifying the second equation, we get:

• 0.08x = 0.40y

We can solve for one variable in terms of the other in the first equation:

• y = P 120,000 - x

Substituting this into the second equation, we get:

• 0.08x = 0.40(P 120,000 - x)

Expanding and simplifying:

• 0.08x = P 48,000 - 0.40x
• 0.48x = P 48,000
• x = P 100,000

So Dylan invested P 100,000 at 8% and P 20,000 at 10%.
