At a breakfast buffet, 93 people chose coffee and 47 people chose juice. 25 people chose both coffee and juice. If each person chose at least one of these beverages, how many people visited the buffet?
number of people = 93+47-25 = ....
To find out how many people visited the buffet, we need to find the total number of people who chose coffee, the total number of people who chose juice, and subtract the number of people who chose both coffee and juice.
Given:
Number of people who chose coffee = 93
Number of people who chose juice = 47
Number of people who chose both coffee and juice = 25
To get the total number of people who visited the buffet, we need to sum up the number of people who chose coffee and the number of people who chose juice, but we need to avoid counting the people who chose both twice.
Let's calculate it step by step:
1. Start with the total number of people who chose coffee (93).
2. Add the total number of people who chose juice (47).
3. Subtract the number of people who chose both coffee and juice (25).
Mathematically, the formula looks like this:
Total number of people who visited the buffet = (number of people who chose coffee) + (number of people who chose juice) - (number of people who chose both coffee and juice)
Plugging in the given numbers,
Total number of people who visited the buffet = 93 + 47 - 25
Simplifying the equation:
Total number of people who visited the buffet = 93 + 47 - 25
Total number of people who visited the buffet = 140 - 25
Total number of people who visited the buffet = 115
Therefore, 115 people visited the breakfast buffet.
