Answer:
8 × 10⁶
Step-by-step explanation:
The first digit can be any number from 2 to 9. We can select any of the eight digits.
We can select the remaining digits in ten different ways.
Each choice is independent, so we can multiply the choices together.
N = 8 × 10 × 10 × 10 × 10 × 10 × 10
= 8 × 10⁶ possibilities
There are 8 × 10⁶ possible seven-digit phone numbers.
