Find the percent of change on an item that was $44 and now costs $66

(66-44)/44=0.5=50%

Step-by-step explanation:

The Percent of change should be 50

Step-by-step explanation:    To find the percent of change you have to:

First: work out the difference (increase) between the two numbers you are comparing.

Second: Increase = New Number - Original Number.

Third: divide the increase by the original number and multiply the answer by 100.

Do the math: % increase = Increase ÷ Original Number × 100.

one fourth of 9% = 2.25%
