Question

A company that makes​ hair-care products had 3,000 people try a new shampoo. Of the 3,000 ​people, 18 had a mild allergic reaction. What percent of the people had a mild allergic​ reaction?

Answer 1

60%

Explanation:

There was a total of 3000 people and of those 3000 people only 18 had a mild allergic reaction.

18/3000 × 100 = 60%

Answer 2

0.6% people had a mild allergic​ reaction to the shampoo.

Explanation:

To find out the percentage of the people who got the mild allergic reaction, we are going to divide the number of people (18) who got the allergic reaction and divide it by total number of people who tried the shampoo (3000) and multiply it by 100.

=
`(18)/(3,000)` * 100

=0.006 * 100

= 0.6%
