0.4 % of total people had allergic reaction

Solution:

Given that company that makes hair-care products had 8000 people try a new shampoo

Of the 8000 people 32 had allergic reactions

To find: percent of the people had allergic reaction

From given information,

Total number of people = 8000

Number of people with allergic reactions = 32

percent of the people had allergic reaction is given as:


\text{ percent } =\frac{\text{ Number of people with allergic reactions }}{\text{ Total number of people }} * 100


\rightarrow (32)/(8000) * 100\\\\\rightarrow (32)/(80) = 0.4

Thus 0.4 % of total people had allergic reaction
