Final answer:
The unit rate at which the dog eats dog food is 4 cups per day.
Step-by-step explanation:
The question asks to determine the unit rate of dog food consumption for a dog. To find the unit rate, we must calculate how much the dog eats per day given that it eats 8 cups of dog food in 2 days. To do this, we will divide the total cups of dog food by the number of days.
8 cups / 2 days = 4 cups/day
Therefore, the unit rate in this situation is 4 cups of dog food per day.
