Answer:
9 × 10⁶ = 9,000,000
Step-by-step explanation:
Data provided in the question:
The phone number is of 7 digits
i.e
we have 7 blanks to fill
also,
we have choices from 0-9 i.e 10 number of choices
Now,
the first digit of the number cannot be zero
Thus,
we have only 9 choices out of 10 for the first digit
And, for the rest of the 6 blanks we have 10 choices for each
Therefore,
The total number of different phone numbers can there be in one area code that can be formed
= 9 × 10 × 10 × 10 × 10 × 10 × 10
= 9 × 10⁶
= 9,000,000
