A dog shelter recorded the number of dogs, d, in their care as well as the pounds of dog food, f, the dogs consumed in a day. The table represents the relationship between the number of dogs, d, and the amount of
food they ate, f. Name the independent variable and the dependent variable and explain.

Food (lbs) 20 30 40 50 60

5. Use the table in question 4 to write an equation using d and f to illustrate the relationship between the two
variables. Be sure to write the dependent variable in terms of the independent variable.
