Answer: number of people that had allergic reactions is 0.7%
Step-by-step explanation:
The total number of people that came to try the company's product is 3000
21 out of the 3,000 people had an allergic reaction. We want to determine how many percent of the total number of 3000 people that tried the product is 21 people that had reaction
Percentage of people that had allergic reactions = number of people that had allergic reactions / total number of people that tried the products × 100
Percentage of people that had an allergic reaction
= 21/3000× 100
= 0.007 × 100 = 0.7%
