Question

Part 1 of 2

A company that makes hair care products had 6,000 people try a new shampoo. Of the 6,000 people, 48 had a mild allergic reaction. What percent of the people
had a mild allergic reaction?

Answer 1

Hi there!

We must begin by finding the decimal value of the proportion.

`\text{Proportion of allergic reactions = }\frac{\text{Amount of people with reactions}}{\text{total amount of people}}`

Substitute in the given values:

`p = (48)/(6000) = 0.008`

This is the decimal value. We must multiply by 100 to get the percentage:

`0.008 * 100 = \boxed{0.8\%}`
