A company conducted a survey to see whether its new toothpaste was morepopular with children or adults. Of the children surveyed

Naily [24]

Given: The information provided in the table shown

To Determine: From the options provided, the correct option that best describe the information given in the table

Solution

Given that 28% of the children used toothpaste. From the table

$Children(toothpaste)=\frac{0.07}{0.25}=\frac{7}{25}\times100=28\%$

Let us calculate the percentage of adult that used toothpaste

$Adult(toothpaste)=\frac{0.08}{0.75}=\frac{8}{75}\times100=10.667\%\approx11\%$

Hence, a smaller percentage of adults (about 11%) use the toothpaste.

The correct option is OPTION C
