A shop sells pens in packs of 3 and notebooks in packs of 5. Andi buys 4 packs of pens and 3 packs of notebooks. He gives the cashier Rp100,000. If a pen pack costs Rp7,500 and a notebook pack costs Rp12,000, how much change does he get?
- A.Rp34,000
- B.Rp30,000
- C.Rp40,000
- D.Rp36,000
Kunci jawaban & pembahasan
Jawaban: Rp34,000
Total cost = 4×7,500 + 3×12,000 = 30,000 + 36,000 = 66,000; change = 100,000 − 66,000 = 34,000.
