30. From 55 lb to 24 lb

Answer 1

Answer:

Decease in weight by 56.4%

Step-by-step explanation:

From 55 lb to 24 lb,

There is a decrease in the weight from 55 lb to 24 lb.

For the percentage decrease in weight,

Change in weight = 55 - 24

                              = 31 lb

Percentage change in weight = $\frac{\text{Total change}}{\text{Initial value}}\times 100$

                                                  = $\frac{31}{55}\times 100$

                                                  = 56.36%

                                                  ≈ 56.4%

Therefore, there is a decease in weight by 56.4%.
