A student is saving money to buy an English dictionary. She already has Rp120,000 and saves Rp20,000 every week. Her friend has Rp60,000 and saves Rp30,000 every week. After how many weeks will they have the same amount of savings?
- A.4 weeks
- B.5 weeks
- C.6 weeks
- D.8 weeks
Kunci jawaban & pembahasan
Jawaban: 6 weeks
Let w be the number of weeks. From 120,000 + 20,000w = 60,000 + 30,000w, we get 60,000 = 10,000w, so w = 6.
