29. original amount: 20; new amount: 35
30. original amount: 70; new amount: 55
29. Percent Change = ((New Amount - Original Amount) / Original Amount) * 100
Percent Change = ((35 - 20) / 20) * 100

30. Percent Change = ((New Amount - Original Amount) / Original Amount) * 100
Percent Change = ((55 - 70) / 70) * 100
Percent Change = (-15 / 70) * 100
Percent Change = -0.214 * 100
