Rina has 3 boxes of pencils. Each box contains 12 pencils. She gives 5 pencils to her friend and 3 pencils to her sister. Then she buys 2 more boxes of pencils, each containing 10 pencils. How many pencils does Rina have now?
- A.48
- B.50
- C.52
- D.54
Kunci jawaban & pembahasan
Jawaban: 48
First, 3 boxes × 12 = 36 pencils. She gives away 5 + 3 = 8 pencils, leaving 36 - 8 = 28 pencils. Then she buys 2 boxes × 10 = 20 pencils, so total = 28 + 20 = 48 pencils.
