Gabriel had $50. He paid $20 for a pair of boots and $12 for a few pairs of socks. What percentage of his money had Gabriel left?

To find out what percentage of his money Gabriel had left, we first need to calculate how much money he spent.

He paid $20 for a pair of boots and $12 for socks, so the total amount of money he spent is $20 + $12 = $32.

Next, we subtract the amount he spent from the initial amount he had to find out how much money he had left.

$50 - $32 = $18.

Now, we can calculate the percentage of money Gabriel had left. To do this, we divide the amount he had left by the initial amount he had, and then multiply by 100.

($18 / $50) * 100 = 0.36 * 100 = 36%.

Therefore, Gabriel had 36% of his money left.
