Answer 1

0. A) 20% Increase

,

1. B) 12.5% decrease

,

2. C) 100% Increase

,

3. D) 50% decrease

Step-by-step explanation:

To calculate the percentage increase or decrease, we use the formula below:

`\text{Percentage Change=}\frac{Final\text{ Value-Initial Value}}{\text{Initial Value}}*100`

Part A (From 50 to 60)

`\begin{gathered} \text{Percentage Change=}\frac{60\text{-5}0}{\text{5}0}*100 \\ =(10)/(50)*100 \\ =20\% \end{gathered}`

We have a percentage increase of 20%.

Part B From 3200 to 2800

`\begin{gathered} \text{Percentage Change=}\frac{2800\text{-}3200}{\text{3}200}*100 \\ =(-400)/(3200)*100 \\ =-12.5\% \end{gathered}`

We have a percentage decrease of 12.5%.

Part C (From 12 to 24)

`\begin{gathered} \text{Percentage Change=}\frac{24\text{-}12}{\text{1}2}*100 \\ =(12)/(12)*100 \\ =100\% \end{gathered}`

We have a percentage increase of 100%.

Part D (From 60 to 30)

`\begin{gathered} \text{Percentage Change=}\frac{30\text{-}60}{\text{6}0}*100 \\ =(-30)/(60)*100 \\ =-50\% \end{gathered}`

We have a percentage decrease of 50%.

The correct choices are A, B and C.
