Sean and Sierra invited 200 guests to their wedding. If 83% of the guests RSVP with a Yes response and 9% of the guests RSVP with a No response, how many guests did not respond at all? Let's answer step by step:
Yes RSVP responses are 200 x 83% = 166 guests. No RSVP responses are 200 x 9% = 18 guests. Guests who responded are 166 + 18 = 184. Guests who did not respond at all are 200 - 184 = 16. The answer: 16.
