A total of $6600 is deposited into two simple interest accounts. On one account the annual simple interest rate is 5%, and on the second account the annual simple interest rate is 7%. The amount of interest earned for 1 year was $382. How much was invested in each account?
**
let x=amt invested at 5% interest rate (1st acct)
6600-x=amt invested at 7% interest rate (2nd acct)
..
5%x+7%(6600-x)=382
.05x+462-.07x=382
.02x=80
x=4000
6600-x=2600
amt invested at 5% interest rate (1st acct)=$4000
amt invested at 7% interest rate (2nd acct)=$2600
