Question

Decide whether the change is an increase or decrease and find the percent change. Original number = 45 New number = 18 Answer: 60% decrease 60% increase 150% increase 150% decrease

Answer 1

The percentage change can be found below

`\begin{gathered} \text{percentage change = }\frac{\text{ new number}-\text{original number}}{\text{original number}}*100 \\ \text{percentage change=}(18-45)/(45)*100 \\ \text{percentage change}=-60 \\ \end{gathered}`

Since the percentage is negative, this means there is a 60% decrease.
