Question

the number of memebers in a club dropped from 80 to 52 what is the precent of decrease in the number of memebers

Answer 1

Percents are represented by the following expression:

`\text{Total}\cdot\frac{\text{percent}}{100}=\text{equivalent number to the percent}`

The members decreased 80-52=28 members, then:

`80\cdot\frac{\text{percent}}{100}=28`

Isolating the variable percent:

`\begin{gathered} \text{percent}=(28\cdot100)/(80) \\ \text{percent}=35 \end{gathered}`

The number of members decreased 35%
