3 ways this goes wrong. Each one is a named misconception the questions are built to catch.
- Container concavity reversedReverses how a container's widening/narrowing maps to the concavity of height-vs-time.→
- Decay ln-sign / rounding errorSolves an exponential-decay inequality with an ln sign error or rounds down instead of up for a 'least integer hours'.→
- Simple vs compound interestUses simple interest, or the wrong (1+r) exponent, in an annuity/amortization geometric series.→
