Step-by-step reasoning process: Janice had X sentences from yesterday already typed to start with today. Janice typed 6 * 20 = 120 sentences before her break. She typed 6 * 15 = 90 sentences after her break. She typed 6 * 18 = 108 sentences after her meeting. Therefore, she typed 120 + 90 + 108 = 318 sentences today in all. She had to erase 40 sentences, so she had 318 - 40 = 278 sentences that she typed today left. The paper had X + 278 = 536 sentences at the end of today. Thus, she had X = 536 - 278 = 258 sentences typed on the paper to start with today.
The question and answer:
