Reasoning and answer: Matt spent on math and science 30% + 40% = 70% of the time. This means he did homework from these two subjects for 70 / 100 * 150 minutes = 105 minutes. So Matt spent 150 minutes - 105 minutes = 45 minutes doing homework from other subjects.
The answer: 45

Question: Matt did his homework for 150 minutes. He spent 30% of that time on math and 40% on science. He spent the remaining time on other subjects. How much time did Matt spend on homework in other subjects?
She needs 6 appetizers per each of her 30 guests so she needs 6 * 30 = 180 appetizers. She's made 3 dozen deviled eggs, 2 dozen pigs in a blanket and 2 dozen kebabs so she's made 3 + 2 + 2 = 7 dozen appetizers. 7 dozen appetizers is 7 * 12 = 84 appetizers. She needs 180 appetizers and has made 84 so she needs 180 - 84 = 96 appetizers. 96 appetizers, in dozens, is 96 / 12 = 8 dozen more appetizers.
The answer: 8
