Answer 4

Lets say account one is x1 and account two is x2.

Regardless of how much you invest in one the total between x1 and x2 have to be 6000

x1+ x2=6000

We also know the combine investment is (x1*.5) + (x2*.3)=220

You know how two equations with two unknowns now solve for x2. I suggest isolating the x1 in the first equation and plugging that in to the second one.

Answer 5

it would come to 3000
