In class of 24 students, 13 students sold over 150 raffle tikets each and 24-13=11 students sold about 60 tikets each.
1. If 13 students sold over 150 raffle tikets each, then together they sold over 13·150=1950 raffle tikets.
2. If 11 students sold about 60 tikets each, then together they sold about 11·60=660 raffle tikets.
3. All together they sold about 1950+660=2610 raffle tikets. Since 2610>2000, they had achieved their goal.
Answer: yes.
