The 7-digit numbers in each area code have the form ABC-X0X, where X, B, and C can be any digit 0-9 and A is restricted to 2-9. There are two other restrictions: •B and C cannot both equal 1 since these values are designated for other purposes such as 911 (emergency) and 411 (information), and • 555-0100 through 555-0199 are reserved for fictional uses such as in television shows or movies.

The 7-digit numbers in each area code have the form ABC-XXXX, where X, B, and C can be any digit 0-9 and A is restricted to 2-9. There are two
other restrictions:
• B and C cannot both equal 1 since these values are designated for other purposes such as 911 (emergency) and 411 (information), and
• 555-0100 through 555-0199 are reserved for fictional uses such as in television shows or movies. According to these conditions, how many 7-digit numbers are
possible in a single area code?
SELECT ALL THAT APPLY
Your answer:
O (8-10-10-10-10-10-10)-(8-10-10-10-10)-100
O (8-10)-(8+10*) -100
O (8000000)-(80000)-100
O 7,919,900
O 80,000,000
