Question

A company that makes​ hair-care products had 8000 comma people try a new shampoo. Of the 8000 comma ​people, 24 had a mild allergic reaction. What percent of the people had a mild allergic​ reaction?

Answer 1

0.3 percent of the people had a mild allergic​ reaction

Explanation:

Given:

Number of comma people try a new shampoo = 8000

Number of people who had a mild allergic reaction = 24

To Find:

Percent of the people had a mild allergic​ reaction = ?

Solution:

Let the percent of the people had a mild allergic​ reaction be x

Then,

x =
`\frac{ \text{ Number of people with mild allergic reaction}}{ \text {total number of people who used the shampoo}} * 100`

x =
`(24)/(8000) * 100`

x=
`0.003* 100`

x= 0.3
