Problema Solution
Mrs. Carter invested a sum of money at 4%. She invested a second sum. 250$ more than the first sum, at 6%. If the total annual income was 90$, how much did she invest each amount?
Answer provided by our tutors
let
x = the sum invested at 4%
x + 250 = the sum invested at 6%
the total annual income was 90$:
0.04x + 0.06(x + 250) = 90
by solving we find:
x = $750

$750 + $250 = $1,000
Mrs. Carter invested $750 at 4% and $1,000 at 6%.
