A total of $2,600 is invested at 6% and 4% annual interest.
After 1 year the total interest equals $134.
How much money is invested at each interest rate?
let x = amt invested at 6%
It says the total is $2600, therefore:
(2600-x) = amt invested at 4%
A total interest equation, (in decimals)
.06x + .04(2600-x) = 134
Solve for x
