Ответ:
Total cost of the survey = $450
Step-by-step explanation:
Given:
Cost for each person = $1
Liked thin crust = 200 people
Liked thick crust = 270 people
Both crust like = 70 people
50 people did not like either type of crust.
We need to find the total cost of the survey.
Solution:
Number of people who like thin crust or thick crust.
⇒ 200 + 270 - 70
⇒ 470 - 70
⇒ 400
So, 400 people likes thin crust OR thick crust.
And, also 50 peoples did not likes either thin crust OR thick crust.
So, we add 50 people who did not like any type of pizza.
⇒ 400 + 50
Therefore, total cost of the survey = $450
