During June, July, August, November, and December, each of the cages at Ruff's Boarding Kennel is booked. Ruff's has 45 large dog cages. It charges $7 per day to board a large dog, but during the other months, business is slow. Ruff's charges $6 per day for 25 of its cages and its regular price for the rest. On September 14th, Ruff's had all of its $6 per day filled and half of its $7 per day cages full. Calculate the kennel's yield for that night.
