Step-by-step explanation:

To know the number of times Tom will pain the number 8, let determine the numbers of 8 between 1 an 100.

The number of 8 between 1 and 100 is shown below:

8, 18, 28, 38, 48, 58, 68, 78, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89 98.

From the above illustration, the number 8 appears 20 times (note 88 has two 8)

Therefore, Tom will pain the number '8' 20 times
