Q: Janice can type 6 sentences per minute. Today at work, Janice continued working on a paper she started typing yesterday. She typed for 20 minutes, took a break, and typed 15 minutes longer. She then had to erase 40 sentences she had typed incorrectly. After a meeting, she typed for 18 minutes more. In all, the paper had 536 sentences by the end of today. How many sentences did she start with today?
A: 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 answer is 258.

[Question]Marcy's grade is electing their class president. Marcy got three times as many votes as Barry, who got twice as many as 3 more than the number of votes Joey got. If Joey got 8 votes, how many votes did Marcy get?
[Answer]
First, add three to Joey's vote total: 8 votes + 3 votes = 11 votes. Then double that number to find the number of votes Barry got: 11 votes * 2 = 22 votes. Then triple that number to find Marcy's vote total: 22 votes * 3 = 66 votes. The answer is 66.
