The total phone numbers, if the latter ABC is followed, will be 175.
Step-by-step explanation:
We are told that the digits will be in the form ABC and A can take values from 2 – 8, B from 5 – 9 and C from 5 – 9 as well.
This means:
A has 7 possible values (when you count the number of numbers between 2 and 8).
B has 5 possible values.
C has 5 possible values.
Therefore, the total phone numbers, if the latter ABC is followed, will be:
7 x 5 x 5 = 175.
