He has 7 - 2 = 5 other classes. 7.5 hours - 1.5 hours = 6 hours. 6 hours = 360 minutes. 360 / 5 = 72 minutes. Keegan spends 72 minutes in one of his other classes.
The answer: 72

Reasoning and answer: 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: 258

Reasoning and 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: 66
