Question

A company that makes hair-care products had 8,000 people try a new shampoo. Of the 8,000 people,24 had a mild allergic reaction. What percent of the people had a mild allergic reaction?

Answer 1

30%

Step-by-step explanation:

24/8000=x/100

cross multiply (24×100=2400 and 8000×x=8000x) to get 8000x=2400

Use inverse operations to divide 2400 by 8000 = 0.3

0.3×100 to get the percentage out of 100% and youll get 30%
