Question

The circle graph shows the results of a survey. Of those surveyed, 200 said yes. About how many people were surveyed?

Answer 1

250 people

Explanation:

let's first look for the missing 20%,

one way you can solve this is by cross multiplication:

since 80% is 200 then 80% = 200

and we know 20% is x then 20% = x (we use x because we don't know the amount of people)

so then we set it up:

`(x)/(20)` ×
`(200)/(80)`

now we cross multiply:

80x = 4000

= x = 50

now we need to find how many people were surveyed so we do:

200 + 50 = 250

250 people were surveyed
