Stephanie volunteered at the 5k being held at the park near her home. The chart below gives the number of hours Stephanie worked and the total number of runners that passed by her.

Hours (h) Runners (r)
1

150
2 300
3 450
4 600
Based on the table, write an equation for the relationship between the number of hours Stephanie worked and the number of runners that passed her.

r = 150h
r = 150h

r = h/150
r = h/150

r = 150/h
r = 150/h

r = 150 + h
r = 150 + h

To find the equation that represents the relationship between the number of hours Stephanie worked (h) and the total number of runners that passed her (r), you can observe the pattern in the data.

From the chart:

  • For 1 hour, there are 150 runners.
  • For 2 hours, there are 300 runners.
  • For 3 hours, there are 450 runners.
  • For 4 hours, there are 600 runners.

It appears that the number of runners increases by 150 for each additional hour worked. Therefore, the relationship can be described as:

\[ r = 150h \]

So the correct response is: r = 150h.
