Redo this problem by using elimination method on a system of 2 linear equations letting x represent the amount investment A and y be the amount in investment b

Question

Investment A is safer investment with an expected return of 3% and investment b is riskier with an expected return of 7%. A client would like to invest 8,000 and would like to return 4.75%.

Answer 1

x = money put into safe investment

 

y = money put into risky investment

 

The two equations (EQ A) and (EQ B) are setup below.

 

[total money invested]

EQ A:  X + Y = 8000 

 

 

 

[return from safe and risk equals desired outcome]

EQ B: .03x + .07y = .0475(8000)  

 

 

Perform any steps needed to simplify (EQ B) on the right-side of the equal sign and then treat this as a standard system of equations using elimination.
