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:
[tex]5*21*10=1050[/tex]
