I think that if he puts m on municipal bonds , i on industrial, t on treasury and c on CDs then the annual interest would just be 6% of m + 13% of i + 10% of t + 9% of c ?

That's right. Say they put \$100,000 on an industrial bond at 13%, then the annual interest will be \$13,000. The rest is linear-programming.

# Optimisation of bonds

(Asked by: username_0 on 2015-04-26)

I'm doing an optimisation problem but don't understand what the terms mean.

Suppose someone wants to invest $110,000.

They have 4 choices as to what they invest their money into:

* municipal bond yielding 6%,
* an industrial bond yielding 13%,
* Treasury bills at 10%,
* certificates of deposit (CDs) at 9%.

I want to maximise their annual interest (in dollars)

There are some constraints (which I haven't typed) but I just want to know what these terms mean. Say, they invest $27,500 on each one, what would their annual interest be (in dollars)?
