Question

A man invests

$3700
in three accounts that pay
5%,
6%
, and
7%
in annual interest, respectively. He has
3
times as much invested at
7%
than he does at
5%
. If his total interest for the year is
$234
, how much is invested at each rate?

Answer 1

First account $3700 at 7% Interest annually = $259.00
Second account $3700 at 6% interest annually = $222.00
Thirs account $3700 at 5% interest annually = $185.00

He has 3 times as much invested at 7% than he does at 5%.
If his total interest for the year is $234, how much is invested at each rate?
