Step-by-step reasoning process: She first gave away half of her 20 brownies, or 20 / 2 = 10 brownies, to the faculty. The remaining brownies number 20 - 10 = 10 brownies. She gave half of these remaining brownies, or 10 / 2 = 5 brownies, to Carl. This reduced her number from 10 down to 10 - 5 = 5 brownies. Finally, she gave away another 2, leaving her with 5 - 2 = 3 brownies.

Step-by-step reasoning process: 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.
The question and answer:
Question and answer:
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?
