Answer:

80

Explanation:

The wording "130% more" suggests that we have the result of adding 130% of the original number to the original number.* This can be expressed as an equation to be solved for the original number.

__

Let x represent the original number. The given relation is ...

184 = x + 130% × x

184 = 2.30x . . . . . . . . . collect terms (130% = 1.3)

80 = x . . . . . . . divide by 2.3

184 is 130% more than 80.

_____

* One needs to be a little careful here. You will often see the wording ...

"<some number> times more".

Usually the intention there is that the result is <some number> times the original amount. That is, percentages are often treated differently from other number expressions in problems like this.
