Linear Problem Question...?

Question

I dont know if i have the constraints right.
For this problem there is no money amount


Bond A has a return of 7.75%
Bond B has a return of 12%

Invest at least 35% of total amount in Bond A
Find a mix of bonds to obtain at least 8.25% in return on entire amount.

what percentage should be allocated in each bond???

Constraints:

A>35%
A+B>65%


I'm really confused :( :(

Sorry, i meant Linear Programming Question :),,,
see how confused i am?? :)

Answer 1

You don't need amount of money just use 100% or this could be $100. Constraints: all these should have equal to sign under but I can't type that here. A>0 B>0 A+B < 100 A>35 B<65 WHEN YOU GRAPH THIS THE VERTICES WILL BE (35,0) (35,65) (100,0) WHEN YOU PLACE THESE INTO THE EQUATION TO MAXIMIZE I= .0775A + .12B YOU WILL FIND THAT THE MAXIMUM IS AT (35,65)
