Answer:

1050

Explanation:

First, we have to determine how many possibilities each information gives us. That is:

The first digit is a vowel, so we have 5 possibilities;

The second digit is a consonant, so we have 21 possibilities, and

The third digit is a one digit number, so we have 10 possibilities.

Now, we just have to use the fundamental principle of counting, multiplying the values found:

\(5*21*10=1050\)
