Mr. Joshua invested 100000 more than his wife. If they both invested the money at 50% per year and their combined income from the two investments was Php 20000.How much did they invest at each rate?
--------------------
Quantity:: h = s + 100000
Interest:: 0.50h + 0.50s = 20000
---------------------
Modify::
h - s = 100000
5h + 5s = 200000
-------------------
Modify for elimination::
h - s = 10000
h + s = 40000
----
Subtract and solve for "s"::
2s = 30000
s = $15,000 (amt. Mrs. invested)
h = $115,000 (amt. Mr. invested)
