70-291 Self paced book pg 2-50

Hi all,

Help me out here...
The exercise I'm doing has me baffled. I'm calculating the # of subnets and the # of available hosts per subnet.

I do understand this:
The original block address is 207.209.68.0 /27
The internally configured subnet mask is 255.255.255.240 (/2

Then

The # of available subnets is 2
The number of available hosts per subnet is 14

Now this is the one that gets me;
The original block address is 208.147.66.0 /25
The internally configured subnet mask is 255.255.255.248 (/29)

My thoughts were the # of subnets was 16, and the # of hosts per subnet was 6. But the book says its supposed to be 8 subnets? Why?
