Question 332761
Hey,

For this one you need to find the percentage of people in this country that have these devices. You divide 221 by 250 and get .884 multiply this by 100% and you get 88.4%. Therefore, 88.4% of 2,800,000 is simply the product of .884 and 2,800,000, which is 2,475,200 people.

I hope this helps!
