George had $100. He bought a shirt for $24 and he also bought a pair of socks. Then he had $65 left. How much is a pair of socks? Let's be accurate as possible.
George had $100 - $24 = $76 left after buying a shirt. Since he has $65 left after buying a pair of socks, then a pair of socks costs $76 - $65 = $11.
The answer: 11.
