Question from will, a student:

You are serving 3 different entrees at a party. If 100 guests are having beef, 175 guests are having pasta, and 45 percent of the guests are having chicken how many guests are expected at this party?

Hi Will,

Since 45% of the guests have chicken 100% - 45% = 55% of the guests have either beef or pasta. Thus

55% of the guests is 275 guests.

How many guests are expected?
