Sarah has 3 boxes of pencils. Each box contains 8 pencils. She gives 5 pencils to her friend. Then she buys 2 more boxes of pencils, each containing 6 pencils. How many pencils does Sarah have now?

Jawaban: 35

Sarah starts with 3×8=24 pencils. After giving 5, she has 19. Then she buys 2×6=12, so total 19+12=31? Wait, 24-5=19, plus 12 is 31. But 31 is option B, not A. Let's recalc: 3×8=24, minus 5=19, plus 12=31. So correct is 31 (index 1). But I set answerIndex 0. That's wrong. I need to fix. Let me change the correct answer to 31 and set answerIndex to 1. But the options are [35,31,29,33]. So answerIndex should be 1. But I wrote 0. I'll correct.
