Question 771443: How many of the even numbers less than 200 have at least one 2 in them?

You can put this solution on YOUR website!
192 is the largest number less than 200
that has at least one 2
There are 18 decades below 192 that have
18 2's in the units position plus the 20
plus the 22 = 18 + 1 + 1 + 1 = 21 so far
---------------------
There can be either no hundreds digit, or 1
for the hundreds digit, so the number
possible is: +2%2A21+=+42+
hope I got it
