Question

120 lb to 180 lb The percentage change is

Answer 1

Given:

Original value = 120 lb

New value = 180 lb

Let's find the percentage change.

To find the percentage change apply the formula below:

`\text{Percentage change = }\frac{New\text{ value-Original value}}{\text{Original value}}\ast(100)/(1)`

Substitute values into the formula and evaluate.

We have:

`\begin{gathered} \text{Percentage change = }(180-120)/(120)\ast(100)/(1) \\ \\ \text{Percentage change = }(60)/(120)\ast(100)/(1) \\ \\ \text{Percentage change = }0.5\ast100 \\ \\ \text{Percentage change = 50 \%} \end{gathered}`

Therefore, the percentage change is 50%

ANSWER:

50%
