I need some help with implied odds

[Trump34]

A situation came up in a hand that prompted me to clear this up. This $50 FR

I was in the CO w/ facing an EP raise of $1.50(stack 9.50) and a call from MP(stack 9.00). I decided to fold based on what I currently know about implied odds.

Even though I know it doesn't matter the flop would have given me top set. Short stacks annoy me even more now.

I have read that you don't want to call with a PP if the villians stack is not more than 10x's the raised amount.

The problem adding some confusion is that I have seen this range from 8-20x's.

So my ?'s here are:

Did I make the correct play here based on implied odds?

In general is 10x's the correct number?

In general 10x is a good guideline to abide by. The actual 'correct' number is closer to 8x, so if you think you can make 8 x $1.50 ($12) by calling, then calling is correct. In this case i'd probably call along, as there's another caller and if you call there are still 3 people, including the blinds to act after you and they might be more inclined to call along if you do simply because of so many people in the pot. I think your fold is fine too though, as theres very little chance of getting paid off big when you hit.
