Question

Mary lost 30 pounds. Before her diet she weighed 180 pounds. What is the percent of change.

pls help, I have to give this by 3:00 today

Answer 1

percentage change= 500%

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%
