Mary just held tryouts for the high school band. 80% of the 20 flutes got in, half the 30 clarinets got in, 1/3 of the 60 trumpets got in, and 1/10th of the 20 pianists got in. How many people are in the band total?
Let's think: First find the total number of flutes who were accepted: 20 flutes * .8 = 16 flutes. Then find the total number of clarinets who were accepted: 30 clarinets * .5 = 15 clarinets. Then find the total number of trumpets who were accepted: 60 trumpets * 1 / 3 = 20 trumpets. Then find the total number of pianists who were accepted: 20 pianists * 1 / 10 = 2 pianists. Then add the number of each kind of instrument to find the total number of people in the band: 16 flutes + 15 clarinets + 20 trumpets + 2 pianists = 53 people.. The answer is: 53.

In a grocery store, the daily salary of the manager is $5 and the clerk is $2. If there are currently 2 managers and 3 clerks employed in the grocery store, how much is the total daily salary of all the employees of the grocery store?
Let's think: The 2 managers earn $5 x 2 = $10 per day. The daily salary of 3 clerks is $2 x 3 = $6. Therefore the total salary of all employees of the grocery store is $10 + $6 = $16.. The answer is: 16.

John weighs one-quarter times more than what Mary weighs. Mary weighs 20 lbs less than Jamison's weight. If Mary weighs 160 lbs, what's the combined weight of the three?
Let's think: If Mary weighs 160 lbs, Jamison weighs 160 lbs + 20 lbs = 180 lbs. If John weighs one - quarter less than what Mary weighs, he weighs 1 / 4 * 160 lbs = 40 lbs more. The total weight of John is 160 lbs + 40 lbs = 200 lbs. The total weight for the three is 200 lbs + 180 lbs + 160 lbs = 540 lbs.. The answer is: 540.

Fiona completed 36 math questions in an hour. Shirley was able to complete twice as many math questions within that same time, and Kiana completed half of the sum of Fiona and Shirley's math questions. If they each did the same number of questions the following hour, how many math questions did all three girls complete in 2 hours?
Let's think:
Shirley completed 36 x 2 = 72 questions. The sum of Fiona and Shirley's questions is 36 + 72 = 108. Kiana completed 108 / 2 = 54 questions. In one hour, they completed 108 + 54 = 162 questions. In two hours, they completed 162 x 2 = 324 questions.. The answer is: 324.
