Quick question about notation.

[Isura]

Haven't been able to find an answer to this. When people say raise 3xBB, and say the blind is $10, does this mean raise to $30 or $40. I'm following AleoMagus' SNG strategy for $5 + $1, and I'm not sure if I'm overbetting by raising to $40 in this case. Sorry for the newbie question.

3xBB= 30

Thanks.
