The circle graph shows the results of a survey. Of those surveyed, 80 said yes. About how many people were surveyed?

Answer:
134 people
Step-by-step explanation:
we can use cross multiplication to solve this problem:
we know that 60% is 80 people and 40% is x people (we put x because we don't know the exact number of how many people yet)
now we set it up:
[tex]\frac{80}{60}[/tex] = [tex]\frac{x}{40}[/tex]
= 60x = 3200
= x = 53.33333
now we add the two numbers of people up:
53.33333 + 80 = 133.3333
since it is a decimal, it would be safer to assume that there are 134 people
