Question

A company that makes​ hair-care products had 400 people try a new shampoo. Of the 400 people, 16 had a mild allergic reaction. What percent of the people had a mild allergic​ reaction?

Answer 1

Answer:

4% of people had a mild allergic reaction

Step-by-step explanation:

16 is 4% of 400

$y = p\% \times x$

$p\% = y \div x$

$p\% = 16 \div 400$

$p = 0.04$

Convert decimal to percentage

$p\% = 0.04 \times 100 = 4\%$

Answer 2

My Answer:

I am pretty sure it would be around 4%
