WebbSolution. We call the initial price of the phone A initial = 800 and the new price A final = 900. We now use the percentage change formula : Percentage Change = A final − A initial A initial = 900 − 800 800 = 100 800 Percentage Change = 0.125. The percentage change was 12.5 %. This was a 12.5 % increase since the result is positive. WebbOur first step is to change the percentage figure into a decimal. We do this by dividing the figure by 100. So, 10% becomes 10/100 = 0.1. The next step is to multiply the decimal figure by the full amount. So, 0.1 x 200 = 20. This gives you your answer. 10% of 200 is 20. In equation form, where Z is your answer, your equation is Z = (X/100) * Y.
