[Question]Brianna started out with a bag of 24 marbles. She lost four marbles through a hole in the bag. Then, she gave away twice as many marbles as she had lost through the hole in the bag. Finally, her dog ate half as many marbles as Brianna had lost through the hole in the bag. How many marbles did Brianna have remaining?
[Answer]Brianna gave away twice as many marbles as she had lost, or a total of 2 * 4 = 8 marbles. Her dog ate half as many marbles as Brianna had lost through the hole in the bag, or 4 / 2 = 2 marbles. If she started with 24 marbles, then the number of marbles remaining is 24 - 4 - 8 - 2 = 10 marbles. The answer is 10.
Q: Tom decides to open a theater. He knows it will cost $5 per square foot of space that he needs and he needs 12 square feet for every seat in his theater. He wants a 500 seat theater. He also realizes construction will cost twice as much as the land. He has a partner who covers 40% of the cost. How much does Tom spend?
A: He needs 500 * 12 = 6000 square feet. This means it cost $5 * 6000 = $30,000. That means construction comes to $30000 * 2 = $60,000. So the total cost is $60000 + $30000 = $90,000. His partner covers $90,000 * .4 = $36,000. So he has to pay $90,000 - $36,000 = $54,000. The answer is 54000.
Question: Marcy is the lunch monitor in an elementary school cafeteria. She gives 5 time-outs for running, 1 less than five times that number of time-outs for throwing food, and 1/3 the number of food-throwing time-outs for swearing. If each time-out is 5 minutes, how much time do the students spend in time-out total?
Answer: First multiply the number of running time - outs by 5: 5 time - outs * 5 = 25 time - outs. Then subtract 1 from that number to find the number of food - throwing time - outs: 25 time - outs - 1 = 24 time - outs. Then divide that number by 3 to find the number of swearing time - outs: 24 time - outs / 3 = 8 time - outs. Then add the number of each kind of time - out to find the total number: 8 time - outs + 24 time - outs + 5 time - outs = 37 time - outs. Then multiply that number by the length of each time - out to find the total time the students spend in time - out: 37 time - outs * 5 minutes / time - out = 185 minutes. The answer is 185.
[Question]A wheel on a certain machine makes 6 turns every 30 seconds. How many turns does it make in two hours?
[Answer]Since there are 60 seconds in 1 minute, then there are 60 / 30 = 2 sets of 30 seconds in a minute. So a wheel makes 6 x 2 = 12 turns in 1 minute. Since there are 60 minutes in 1 hour, then a wheel makes 12 x 60 = 720 turns in an hour. Therefore, the wheel makes 720 x 2 = 1440 turns in 2 hours. The answer is 1440.
[Question]Sab and Dane sold 6 pairs of shoes that cost $3 each and 18 shirts that cost $2. How much will each of them earn if they divided their total earning?
[Answer]
They earned 6 x $3 = $18 for the shoes they sold. They earned 18 x $2 = 36 for the shirts they sold. So, they earned $18 + $36 = $54 in total for the clothing they sold. Therefore, Sab and Dane earned $54 / 2 = $27 each. The answer is 27.
