Harry ga-eme ka ịmalite, site n'ime silver?``` <response>: First find the total cost of the spellbooks by multiplying the price per book by the number of books: 5 books * 5 gold/book = 25 gold
Then add that amount to the cost of the owl: 25 gold + 28 gold = 53 gold
Now multiply that number by the conversion rate between gold and silver: 53 gold * 9 silver/gold = 477 silver
Now find the total cost of the potion kits by multiplying the price per kit by the number of kit: 3 kits * 20 silver/kit = 60 silver
Now add that amount to the cost of the books and owl to find Harry's total spending: 60 silver + 477 silver = 537 silver

Answer is 537.
