Domain : -5,-3,0,1,2
range : 1,2,3,1,0

If the cost is $138.25 and the desired markup is 12.5%, then what is the price after markup?
KIM [24]
First, you must turn the 12.5% into a decimal, which would then become .125. You then multiply that by the $138.25 and you would get 17.28. Then you just add the $138.25 to the $17.28 where you would then get $155.53 as your answer. Please let me know if I am wrong.
