How many numbers between 0 and 100 contain a 3?

dangerousjesse · Answer

It shouldn't take very long to count them.. :/

dangerousjesse · Answer

I'm just going to assume you know by now, the amount is x. $x\times 10+89=\textsf{the answer}$ The 89 is for all 300's, excluding the ones already counted in $\times 10$
