Question

An internet company randomly selected 50 of its

customers and asked them how many hours per
week they use the internet. Of those surveyed, 28
use the internet more than 15 hours per week.
Based on the data, if the company has 800
subscribers how many watch more than 10 hours
per week?

Answer 1

448 subscribers

Explanation:

First, find the percentage of people that use the internet more than 15 hours per week.

`\%=(28)/(50)=0.56=56\%`

Now, we can use this information to find 56% of 800.

`56\%*800`

Note that percentages can also be written as that number over 100.

`(56)/(100)*800=(44800)/(100)=448\text{ subscribers}`
