enter the number of people mariah surveyed who have been to both canada and mexico

Number of people who had been to Canada and Mexico both are 68.

Step-by-step explanation:

Mariah surveyed 200 people.

- She found 60% of the surveyed people had been to Canada.

That means number of people had been to Canada = 200 × 20%

= 200×

= 120

- She found 42% of the surveyed people had been to Mexico.

That means number of people had been to Mexico = 200 × 42%

= 200×

= 84

It is given that people who never been to Canada = 16

So the people who had been to Mexico only = 16

Since number of people who had been to Mexico = 84

So number of people who had been to Canada and Mexico both = 84 - 16 = 68

Number of people who had been to Canada only = Number of people who never had been to Mexico

= Number of people had been to Canada - Number of people who had been to both Mexico and Canada

= 120 - 68

= 52
