An English club is comparing two printing services for its magazine. Service P charges Rp200,000 for setup plus Rp2,000 per copy. Service Q charges Rp100,000 for setup plus Rp3,000 per copy. For how many copies are the total costs equal?
- A.80 copies
- B.100 copies
- C.120 copies
- D.150 copies
Kunci jawaban & pembahasan
Jawaban: 100 copies
Let c be the number of copies. Setting 200,000 + 2,000c = 100,000 + 3,000c gives 100,000 = 1,000c, so c = 100.
