The book's answer is correct for the part you circled. I didn't check anything else. I verified this using the calculator in Windows, in Programmer mode.
A possible reason for the number you got is that you didn't carry correctly.

I get the book solution.
You have B * AFC4 = 6E000 + A500 + 840 + 2C and the 6E000 + A000 = 78000
