Question

The table shows the relationship between the wait time in minutes and the number of people in line. Is there a direct variation? If so, what is the constant of proportionality (k)? *

1. No, there is no direct variation
2. Yes, there is a direct variation; k = 13 minutes per person
3. Yes, there is a direct variation; k = 17 minutes per person
4. Yes, there is a direct variation; k = 20 minutes per person
5. Other:

Answer 1

the variation is 1:20 or 1 to 20

Explanation:

4 to 80

8 to 160

12 to 240

16 to 320

4,8,12,16

80,160,240,320.

they are all equal because if we take

4 x 20 = 80

8 x 20 = 160

12 x 20 = 240

16 x 20 =320
