To find the unit rate, we divide the number of copies by the time in minutes.
- For 0 minutes, the girl shows 50 copies. The unit rate would be 50/0, which is undefined.
- For 1 minute, the girl shows 50 copies. The unit rate would be 50/1, which is 50.
- For 2 minutes, the girl shows 100 copies. The unit rate would be 100/2, which is 50.
- For 3 minutes, the girl shows 150 copies. The unit rate would be 150/3, which is 50.
- For 4 minutes, the girl shows 200 copies. The unit rate would be 200/4, which is 50.
- For 5 minutes, the girl shows 250 copies. The unit rate would be 250/5, which is 50.
- For 6 minutes, the girl shows 300 copies. The unit rate would be 300/6, which is 50.
- For 8 minutes, the girl shows 400 copies. The unit rate would be 400/8, which is 50.
The unit rate is consistent at 50 copies per minute. Therefore, the correct answer is b) 50.
