Holly invested two equal amounts of money, one at 4.5% and the other at 5% simple interest.
 Her total annual interest from the two investments was Php7,600. How much did she put in at each rate?
:\
Let a = amt invested at each rate
:
.045a + .05a = 7600
.095a = 7600
a = 7600/.095
a = $80,000 at each rate
