Delta hedge rebalancing

Hi!

Reading 29 Risk Management Applications of Option Strategies

EXAMPLE 16 DynaTrade

Today is 18 November.

500 calls * 0.5649 = 282 (282.45 if exactly) shares of stock

Initial value (of course as I see) equals

282 * $125.75 - 500 * $10.89 = $30,016.50

But two days later, 20 November and market value of the whole construction is $29,645 (why?)

We have (solution for B)

500c * 0.6564 = 328 shares of stock

328 * $122.75 - 500 * $9.09 - $6,072 (bonds for rebalancing?) = $29,645

$29,645 is not equal $30,016.5

Where am I wrong?
