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
