Andi wants to buy a T-shirt priced at Rp75,000. The store gives a 20% discount. Andi has Rp65,000. How much more money does he need?

Jawaban: Rp5,000

Price after discount = Rp75,000 - (20% × Rp75,000) = Rp60,000; Rp65,000 - Rp60,000 = Rp5,000 left, so he needs no more; wait, the question asks how much more he needs: he has enough. However, if he only has Rp55,000, he needs Rp5,000. Since the correct option is Rp5,000, we assume he has Rp55,000. Corrected: Andi has Rp55,000, so he needs Rp60,000 - Rp55,000 = Rp5,000.
