100 * 97

The question if you look at it asks how many times the number 8 will be painted. The answer is just 1 single digit 8 alone. The question was not how many times the 8 would be used..

It’s twenty because when you paint “88” that counts as two 8’s.

The answer is 19. The 88 seems to have been counted twice.

Ooops, I see my mistake. There are 19 numbers containing “8” but you would paint “8” 20 times.

NO, you have counted 88, twice.

Over the range of 1 to 100, there are 10 numbers with an 8 in the 10’s place (80–89) and 10 numbers with 8 in the 1’s place (8, 18, 28, 38, …, 98). Josh would thus paint the number 8 twenty times.

how did the answer came up to 20 times?
