Harvey's started out with 25 steaks. Then he sold some, and only had 12 steaks left. He sold 4 more steaks, at 10 dollars. How many steaks did he sell in all? Let's be accurate as possible.
Harvey sold 25 - 12 = 13 steaks at first. Harvey then sold more steaks for a total of 13 + 4 = 17 steaks.
The answer: 17.
