Answer this question:Hannah wants to get the highest grade in the class on the upcoming math test. Because she is out sick the day of the test, she learns ahead of time the top scores she has to beat. She finds out that one student got a 95% on the exam. Another student only got 3 wrong out of 40. How many questions does she have to get right to have the highest score in the class?
One student got 37 questions right because 40 - 3 = 37. This student's proportion right is .925 because 37 / 40 = .925. This student got a 92.5% because .925 x 100 = 92.5. The student got got a 95% got 38 right because 40 x .95 = 38. Hannah must beat the student who got a 38 because 38 > 37. Hannah needs to get 39 questions right because 38 + 1 = 39.
The answer is 39.

Answer this question:Miriam has five times as many albums as Katrina. Katrina has six times the number of albums as Bridget. Bridget has 15 fewer albums than Adele. How many albums do they have together if Adele has 30 albums?
Since Adele has 30 albums, and Bridget has 15 fewer, Bridget has 30 - 15 = 15 albums. Together, Bridget and Adele has 30 + 15 = 45 albums. Katrina has six times the number of albums as Bridget, a total of 15 * 6 = 90 albums. Adele, Bridget, and Katrina have a total of 90 + 45 = 135 albums together. Miriam has five times the number of albums as Katrina, a total of 5 * 90 = 450 albums. Together, Adele, Bridget, Katrina, and Miriam have 135 + 450 = 585 albums.
The answer is 585.

Answer this question:A carnival snack booth made $50 selling popcorn each day. It made three times as much selling cotton candy. For a 5-day activity, the booth has to pay $30 rent and $75 for the cost of the ingredients. How much did the booth earn for 5 days after paying the rent and the cost of ingredients?
The booth made $50 x 3 = $150 selling cotton candy each day. In a day, the booth made a total of $150 + $50 = $200. In 5 days, they made a total of $200 x 5 = $1000. The booth has to pay a total of $30 + $75 = $105. Thus, the booth earned $1000 - $105 = $895.
The answer is 895.

Answer this question:Jane runs 3 kilometers in two hours. What is her speed in meters per minute?
Since 1 kilometer is equal to 1000 meters, then 3 kilometers is 3 x 1000 = 3000 meters. Since an hour has 60 minutes, then 2 hours is equal to 2 x 60 = 120 minutes. Therefore, her speed is 3000 meters / 120 hours = 25 meters per minute.
The answer is 25.
