Haley spends 2 hours shopping for a telescope, 0.5 hours setting up, and 3 times the setup time making snacks, which is 3 * 0.5 = 1.5 hours making snacks.
So in total, she spends 2 + 0.5 + 1.5 = 4 hours on those activities.
She also spends 20 minutes watching the comet, which is 20/60 = 1/3 hours.
Therefore, the percentage of time spent watching the comet is (1/3)/(4) * 100 = 8.33%
Rounding to the nearest percent, the answer is 8%
#### 8
