Let
s = the money invested in stocks
b = the money invested in bonds
A person invested $25,000 in stocks and bonds:
s + b = 25000
Her investment in bonds is $5,000 more than one third her investment in stocks:
b = 5000 + (1/3)s
by solving the system of equations:
s + b = 25000
b = 5000 + (1/3)s
we find:
s = $15,000
b = $10.000
