Step-by-step reasoning process: For 6 months, Shara was able to return $10 x 6 = $60 to her brother. Since she already returned half of the money, then this means she currently owes her brother $60. Four months from now, she will be able to pay an additional $10 x 4 = $40. Thus, she will still owe her brother $60 - $40 = $20 four months from now.
[Q & A] The question is Shara borrowed money from her brother 6 months ago. She returned $10 per month to her brother. Currently, she was able to return half of the money she borrowed. How much will she still owe her brother 4 months from now?
The answer is 20

Step-by-step reasoning process: 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.

Step-by-step reasoning process: If she invited 20 friends, then the number of friends who came with one more person is 1 / 2 * 20 = 10. If the 10 friends came with 10 more people, the total number of guests becomes 20 + 10 = 30 guests. If you add Ashley, the total number of people in the party is 30 + 1 = 31 people.
