hram777 [196]

Answer: Percent of people who had a mild allergic is 0.6%.

Step-by-step explanation:

Total number of people try a new shampoo = 7000

Number of people had a mild allergic reaction = 42

We need to find the "Percentage of people had a mild allergic":

Percentage of people had a mild allergic is given by

$\frac{\text{ Total number of people who had a mild allergic}}{\text{ Total number of people}}\times 100\\\\=\frac{42}{7000}\times 100\\\\=\frac{42}{70}\\\\=0.6\%$
