Answer:

percentage change= 500%

Step-by-step explanation:

After diet the weight reduced = 30 pounds

Before diet her weight = 180 pounds

percentage change = { (180 - 30) ÷ 30 } × 100

                             =  ( 150 ÷ 30) × 100

                              = 5 × 100

                               = 500 %

∴percentage change= 500%
