The circle graph shows the results of a survey. Of those surveyed, 10 said no. About how many people were surveyed?

Answer:
50 people
Step-by-step explanation:
so to solve this we can use cross multiplying:
first we know that 20% = 10 people and 80% = x people (we put x because we don't know how many people)
then we set it up:
[tex]\frac{10}{20}[/tex] = [tex]\frac{x}{80}[/tex]
= 20x = 800
= x = 40
now it asks how many people were surveyed in total so we add the 10 + 40 = 50
50 people were surveyed
