Q: Maria is a saleswoman at a flower shop. On the first day, she sold 30 tulips and 20 roses. The next day, she doubled the previous day's sales. On the third day, she sold only 10% of the tulips sold on the second day and 16 roses. The price of one tulip is $2 and one rose is $3. How much did Maria earn over these three days?
A: On the second day, Maria sold 30 * 2 = 60 tulips. She also sold 20 * 2 = 40 roses the second day. On the third day, Maria sold only 10 / 100 * 60 = 6 tulips. Over these three days Maria sold 30 + 60 + 6 = 96 tulips. She also sold 20 + 40 + 16 = 76 roses. So on the tulips Maria earned 96 * 2 = $192. And on roses Maria earned 76 * 3 = $228. In total, over these three days, Maria has earned 192 + 228 = $420. The answer is 420.

Q: A row of houses all share a community space where they put up their clotheslines. There are 2 clotheslines for every house on the street. On the street, there are a total of 11 children and 20 adults. Each child currently has 4 items of clothing on the clotheslines and each adult currently has 3 items of clothing on the clotheslines. If each clothesline can hold 2 items of clothing and all of the clotheslines are full, how many houses are on the street?
A: From the children, there are a total of 11 children * 4 items of clothing each = 44 items of clothing on the clotheslines. From the adults, there are a total of 20 adults * 3 items of clothing each = 60 items of clothing on the clotheslines. So there are a total of 44 + 60 = 104 items of clothing on the clotheslines. This means that there are 104 items of clothing / 2 items of clothing per clothesline = 52 clotheslines. There are 2 clotheslines per house so there must be 52 clotheslines / 2 = 26 houses on the street. The answer is 26.
Question: The football coach makes his players run up and down the bleachers 40 times. Each time they run up and down 32 stairs one way. If each stair burns 2 calories, how many calories does each player burn during this exercise?
Answer: First find the number of stairs the players climb up and down each time: 32 stairs * 2 = 64 stairs. Then multiply the number of stairs per run by the number of runs to find the total number of stairs the players climb: 64 stairs / run * 40 runs = 2560 stairs. Then multiply the number of stairs by the number of calories each stair burns: 2560 stairs * 2 calories / stair = 5120 calories. The answer is 5120.
