A man 2

A man divides $10,000 into two investments, one at 10% and the other at 30%. Find how much is invested at each rate so that the two investments produce the same income annually.

Result

a =  7500
b =  2500

Solution:


a+b=10000
0.10*a = 0.30*b

a+b = 10000
0.1a-0.3b = 0

a = 7500
b = 2500
