[Question]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?
[Answer]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. The answer is 20.

A: The 2nd competitor ate twice the amount of the 1st competitor's 12 hot dogs So he ate 2 * 12 = 24 hot dogs. The 3rd competitor ate 25% less than the 2nd's 24 hot dogs, which is 24 / 4 = 6 hot dogs. If the 2nd competitor ate 24 hot dogs, and the 3rd ate 25% less than that, then the 3rd competitor ate 24 - 6 = 18 hot dogs. The answer is 18.
Question: 3 families of 4 people shared a vacation rental for 7 days. Everyone uses 1 oversized beach towel a day before getting a new one. The washing machine can hold 14 oversized beach towels per load. How many loads of laundry will it take to wash all the oversized beach towels?
Answer:
There are 3 families of 4 meaning there are 3 * 4 = 12 people in the vacation rental. They all use 1 oversized beach towel a day so they use 1 * 12 = 12 towels a day. They use 12 towels a day for 7 days so in one week they use 12 * 7 = 84 beach towels. The washing machine can only hold 14 towels and they have 84 towels to wash which means there are 84 / 14 = 6 loads of laundry. The answer is 6.
