Bill invests in a plan that has an interest rate of 2%. He invests two times as much in a plan that has an interest rate of 3%. If the total interest from the investments is $ 336 after one year how much was invested in each plan?
---------------
Equation:
interest + interest = interest
0.02x + 0.03(2x) = 336
-----
2x + 6x = 33600
8x = 33600
x = $4200 (amt. invested in the 2% plan)
2x = $8400 (amt. invested in the 3% plan)
