A dog kennel feeds some dogs dry food and some dogs wet food. The kennel uses 13 1/2 cups of dry dog food and has 7 dogs that each eat an equal amount of wet dog food. The total amount of food the kennel uses is 25 3/4 cups. Write an equation that can be used to determine the amount of wet food each dogs gets?
