How many possible license plates can be made with 4 letters followed by 4 numbers and must start with the letter C

1 * 26^3 * 10^4 = 175760000

To find the number of possible license plates that can be made with these criteria, we need to consider the number of options for each position.

For the 4 letter positions, we can use any letter from the alphabet except for C, as the license plates must start with the letter C. There are 25 options for each letter position, since there are 26 letters in the alphabet minus the letter C.

For the 4 number positions, we can use any digit from 0 to 9. Therefore, there are 10 options for each number position.

To calculate the total number of possible license plates, we need to multiply the number of options for each position together.

Number of options for the 4 letter positions = 25 * 25 * 25 * 25 = 390,625
Number of options for the 4 number positions = 10 * 10 * 10 * 10 = 10,000

Total number of possible license plates = Number of options for the 4 letter positions * Number of options for the 4 number positions
= 390,625 * 10,000 = 3,906,250,000

Therefore, there are 3,906,250,000 possible license plates that can be made with 4 letters followed by 4 numbers and must start with the letter C.
