Show solution outline
Error of principle — wrong category (expense vs asset).
Effect on profit: Overstated expenses → profit understated by $4,000 (no depreciation yet).
Effect on SOFP: Non-current assets understated $4,000; no effect on TB balance.
Correction: DR Office equipment $4,000, CR Purchases $4,000 — then depreciate and adjust profit.
