-	The actual cost of the options might be $2000 in cash. That means $2000 is giving a notional exposure of $28620 in the S&P 500.
+	The actual cost of the options might be $12700 in cash. That means $12700 is giving a notional exposure of $28620 in the S&P 500.

	This gives an overall leverage ratio of:

	```math
-	\frac{(100000 + 28620)}{(100000 - 2000)} = \frac{128620}{98000} = 1.31
+	\frac{(100000 + 28620)}{(100000 - 12700)} = \frac{128620}{87300} = 1.47
