2. 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?
To find the total number of people who visited the buffet, we need to add the number of people who chose coffee, the number of people who chose juice, and subtract the number of people who chose both coffee and juice.
Let's break it down:
Number of people who chose coffee = 93
Number of people who chose juice = 47
Number of people who chose both coffee and juice = 25
Now, to calculate the total number of people who visited the buffet:
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
Total number of people who visited the buffet = 93 + 47 - 25
Total number of people who visited the buffet = 140
Therefore, 140 people visited the breakfast buffet.
