Divide a percent by 100 to get it into a decimal form.
14%/100 = 0.14
--------------
To add the percent onto a number, we must multiply the number by (1 + the percent)
This can be written as: X+%2B+0.14X or simply 1.14%2AX
So: X+%2A+1.14+=+456
Divide both sides by 1.14
highlight%28X+=+400%29
The original cost of the suit was $400
