A total of $5000 is invested in two accounts. One account pays 6% annual interest and the other pays 8% annual interest. If the total annual interest from both accounts is $360, how much is invested at 6%?
✓ Correct Answer: Option B
Let x be the amount at 6% and y at 8%. x + y = 5000 and 0.06x + 0.08y = 360. Solving this system gives x = $2000.
