Question

A recent survey found that 66.9% of Americans can use the Internet. If a city has a population of 76,000 how many people in that city would you expect to use the Internet?

Answer 1

Wouldn't you expect 66.9% of them?

Answer 2

well i assume it meant that 66.9% is the percent for the USA but it wants to know for just that city... i think

Answer 3

I think we could make the logical assumption that it would most likely also be close to 66.9% of the city.

Answer 4

Do you get it?

Answer 5

noo ha

Answer 6

Lets look at a simpler example.. I promise this will help just bare with me

Answer 7

ok

Answer 8

Okay so here is a separate example:

Answer 9

If half the people in the US use internet would you also expect half the people in a large city to use internet?

Answer 10

The answer is yes!
Since half of all the people use the internet, if we look a large city we would also expect half of the city to use the internet.

Answer 11

It would be quite weird if there was an entire city where no one used the internet 0.o

Answer 20

Answer 21

No back to the original question:
A recent survey found that 66.9% of Americans can use the Internet. If a city has a population of 76,000 how many people in that city would you expect to use the Internet?

Answer 22

In the first example we saw 50% of all people using the internet and also 50% of the city using the internet.

Answer 23

In this example we see 66.9% of all the people using the internet, so 66.9% of the city must use the internet as well.

Answer 24

So then what the heck is 66.9% of the city?

Answer 25

well 66.9% is the same as .669

Answer 26

in math, the word "of" means "multiply"

Answer 27

and the city has 76,000 people

Answer 28

So:
66.9% of 76,000
is the same as
\(.669 \times 76,000 \)

Answer 29

just type that into your caulator.. or even google and you are done
