0.2 % people had a mild allergic reaction

Solution:

A company that makes hair care products had 7,000 people try a new shampoo

Of the 7,000 people 14 had a mild allergic reaction

To find: Percent of the people had a mild allergic reaction

The Percent of the people had a mild allergic reaction is found by dividing number of people has mild allergic reaction by total number of people and multiply the result by 100

Number of people has mild allergic reaction = 14

Total number of people = 7000

$percent = \frac{\text{Number of people has mild allergic reaction}}{\text{total number of people}} \times 100$

$percent = \frac{14}{7000} \times 100\\\\percent = \frac{14}{70}\\\\percent = 0.2$

Thus 0.2 % people had a mild allergic reaction
