Budi buys 3 pens for Rp4,500 each and 2 notebooks for Rp7,000 each. He pays with a Rp50,000 note. How much change does he receive?

Jawaban: Rp21,500

Pens = 3 × Rp4,500 = Rp13,500. Notebooks = 2 × Rp7,000 = Rp14,000. Total = Rp27,500. Change = Rp50,000 − Rp27,500 = Rp22,500? Wait, recalculate: 13,500 + 14,000 = 27,500. Change = 50,000 − 27,500 = 22,500. Correct answer should be Rp22,500. Let me fix options.
