The answer is 225.

To solve for the answer, we need to equate the given data.
> [360 + (360 )25%]= ?
First we need to convert percentage into fractions.
> [360 + (360)1/4]= ?
The next step is to follow PEMDAS
> 360 + 90
> 450
The next question is to decrease the result(450) by 50%.
Multiply (450) by 50%.
> (450) (50%)
Change the percentage into fraction.
> (450) (½)
Then multiply the numbers.
> (450) (½)
>  225.
