Helen cuts her lawn starting in March and finishes in October. Her lawn mower uses 2 gallons of gas every 4th time she cuts her lawn. For March, April, September and October, she only cuts her law 2 times per month. In May, June, July and August, she has to cut her lawn 4 times per month. How many gallons of gas will she need to cut her lawn from March through October? Give the rationale and then the answer.
Let's think step by step. For March, April, September and October, she cuts her lawn 2 a month. There are 4 months so she cuts her yard 2 * 4 = 8 times. For May, June, July and August, she cuts her lawn 4 times a month. There are 4 months so she cuts her yard 4 * 4 = 16 times. During the entire 8 month period, she cuts her lawn 8 + 16 = 24 times. Every 4th time she cuts, she needs 2 gallons of gas. If she cuts her lawn 24 times a year then she needs to fill up 24 / 4 = 6 times. Each time she fills up, it takes 2 gallons of gas so 2 * 6 = 12 gallons of gas per year.. The answer is: 12.

Hannah collects mugs. She already has 40 different mugs in 4 different colors. She has three times more blue mugs than red mugs and 12 yellow mugs. Considering that she has only half as many red mugs as yellow mugs, how many mugs of another color than mentioned does she have? Give the rationale and then the answer.
Let's think step by step. Hannah has half as many red mugs as yellow mugs, which means she has 12 * 0.5 = 6 red mugs. Hannas has three times more blue mugs than red ones, which means 3 * 6 = 18 blue mugs. So there are 40 - 18 - 6 - 12 = 4 mugs in a different color than mentioned.. The answer is: 4.

During a school meeting, 300 students and 30 teachers are seated but 25 students are standing. How many attended the school meeting? Give the rationale and then the answer.
