100

Step-by-step explanation:

the first digit can only be 1 thing: the letter c.

The second and third digits can make up number anywhere from 00 to 99. there are about 100 variations of the second and third digits, and 10 possibilities individually. multiply the 1 from the first digit and the 10 from the second and the 10 from the third to get 100.
