To calculate the entry fee for someone from Britain, we need to count the number of vowels and consonants in the country name and use the given formula.

Country: Britain

Vowels: 2 (i, a)
Consonants: 5 (b, r, t, n)

Using the formula where vowels are worth $300 and consonants are worth $200, the entry fee for someone from Britain would be:

(2 x $300 + 5 x $200) = $600 + $1000 = $1600

So, the entry fee for someone from Britain is $1,600.

Explanation:
- The Wire of the extension cord-1 is broken.
- The extension cord-6 does not have a wire.
- One of the sockets of cord-2 is broken
- The cord-4 with just one socket is of no use.

Now,
- Cord-1 will connect to the main switch and one of the sockets will connect to Cord-2.
So two sockets can be used from cord-1.

- One of the sockets of cord-2 will connect to the cord-5 and one of them is useless.
So two sockets can be used from cord-2.

- Cord-5 can use all the sockets, i.e. 4

So,
Total In Use = 2 + 2 + 4 = 8.
