[Question]: 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?
[Answer]: 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.
So the answer is 16.

[Question]: Carolyn is planning out her final essay. The introduction will be 450 words, the conclusion will be triple the length of the introduction, and each of the four body sections will be the same length. If her essay has to be 5000 words total, how long is each section?
[Answer]: First find the length of the conclusion by tripling the length of the introduction: 450 words * 3 = 1350 words. Then subtract the length of the introduction and conclusion from the total length to find the combined length of the body sections: 5000 words - 1350 words - 450 words = 3200 words. Then divide the combined length of the body section by the number of body sections to find the length of each section: 3200 words / 4 sections = 800 words / section.
So the answer is 800.

[Question]: James spends 40 years teaching. His partner has been teaching for 10 years less. How long is their combined experience?
[Answer]:
His partner has been teaching for 40 - 10 = 30 years. So together they have 40 + 30 = 70 years of experience.
So the answer is 70.
