You can put this solution on YOUR website!
Let x be part of the $120,000 we wish to invest under 5% interest.
120000-x will be the other part of our $120,000 that we invest in the low-risk stock that earns 1%. With that we can set up our equation.

.05x + (120000-x)*.01 = 4400
.05x + 1200 - .01x = 4400
.04x = 3200
x = 80000
120000-x = 120000-80000 = 40000
5% : 80000
1% : 40000
