The quantities in the data table are in a proportional relationship. Using the data in the table, show your work and explain how you know the table represents a proportional relationship.

To determine if the table represents a proportional relationship, we need to check if the ratio of money to hours is constant throughout the table.
Let's calculate the ratio for each row:
For the first row:
money / hours = 9 / 1 = 9
For the second row:
money / hours = 18 / 2 = 9
For the third row:
money / hours = 27 / 3 = 9
For the fourth row:
money / hours = 36 / 4 = 9
As we can see, the ratio of money to hours is consistently 9 throughout the table. This constant ratio indicates that the table represents a proportional relationship.
