One of the most common mistakes on DAT investment problems is confusing total value with total profit.
Total investment = 50,000
Total accumulated value = 54,300
Actual profit = 4,300
The equation must reflect profit:
0.14x + 0.02(50,000 − x) = 4,300
Once the setup is correct, the algebra is straightforward.
