Stan invests $5000, some at 6% interest and the rest at 4.5% interest. If x is the amount he invests at 6%, then the amount invested at 4.5% can be expressed as

A.045x.
B10.5x.
C5000 - x.
D5000 + x.

Verified Answer :

Let's say that Stan invested $1500 at 6%.  To find how much he invested at 4.5% would be 5000 - 1500 = $3500.  Now we have a pattern.  Now let's say stan invested x dollars. Even though it is unknown, we can set up how much is left.  So subtract x from 5000 or 5000 - x which is C

Answer:

C) 5000 - x.
