Initial cost = $126 Final cost = $150 Then Amount of change = (150 - 126) dollars = 24 dollars Then Percentage change = (24/126) * 100 = 2400/126 percent = 19.05 percent So from the above deduction we can easily conclude that the percentage change is 19.05%. I hope the procedure is simple enough for you to easily understand. You can generally use this method for solving similar kind of problems in future without requiring any kind of help from outside.
