Question

Original amount: 25End amount: 18

Answer 1

The formula to calculate the percentage change is given as

`\text{Percentage Change = }\frac{Original\text{ Amount}-\text{Final Amount}}{Original\text{ Amount}}*100`

The question gives us:

Original amount: 25

End amount: 18

Substituting, we have

`\begin{gathered} C=(25-18)/(25)*100 \\ =(7)/(25)*100 \\ =28 \end{gathered}`

The percentage change is a 28% decrease.
