[Question]As firefighters, Doug, Kai, and Eli have been putting out a lot of fires over the week. Doug has put out 20 fires for the week and Kai has put out 3 times more than Doug. Meanwhile, Eli has put out half the number of fires Kai was able to. How many fires have they put out for the entire week?
[Answer]Kai has put out 20 x 3 = 60 fires for the week. Eli has put out 60 / 2 = 30 fires for the week. Therefore, the total amount of fires they have put out over the entire week was 20 + 60 + 30 = 110. The answer is 110.
Q: If Billy rode his bike 17 times, John rode his bike twice as many times, and their mother rode her bike 10 times more than John, how many times did they ride their bikes in total?
A: To find the number of total bike rides, we must first determine how many times John rode his bike. We do this by performing 17 * 2 = 34 times for John. Since John's mother rode 10 times more than John did, we find her total by performing 34 + 10 = 44 times. For all three people put together then, we perform 44 + 34 + 17 = 95 times in total. The answer is 95.
Question: Akeno spent $2985 to furnish his apartment. Lev spent one-third of that amount on his apartment and Ambrocio spent $177 less than Lev. How many dollars more did Akeno spend than the other 2 people combined?
Answer: Lev = (1 / 3) * 2985 = $995. Ambrocio = 995 - 177 = $818. 2985 - (995 + 818) = $1172. Akeno spent $1172 more than Lev and Ambrocio combined. The answer is 1172.
[Question]Darnell has 1000 square feet of fabric that he's using to make mini flags. He makes square flags that are 4 feet by 4 feet, wide rectangular flags that are 5 feet by 3 feet, and tall rectangular flags that are 3 feet by 5 feet. He has already made 16 square flags, 20 wide flags, and 10 tall flags. How many square feet of fabric does he have left?
[Answer]The square flags use 16 square feet of fabric per flag because four times four equals 16. The wide flags each use 15 feet of fabric per flag because five times three equals 15. The tall flags each use 15 feet of fabric per flag because five times three equals 15. He has used 256 square feet for the square flags because 16 times 16 equals 256. He has used 300 square feet for the wide flags because 20 times 15 equals 300. He has used 150 square feet for the tall flags because ten times 15 equals 150. He has used 706 square feet because 256 plus 300 plus 150 equals 706. He has 294 square feet left because 1,000 minus 706 equals 294. The answer is 294.
Q: Mr. Grey's house was worth $100,000. He sold the house to Mr. Brown at a profit of 10%. After one year, Mr. Brown sold the house to his other friend with a 10% loss. How much was Mr. Brown's selling price?
A: Mr. Grey had a $100 000 x 10 / 100 = $10,000 profit. So, Mr. Grey sold the house to Mr. Brown for $100 000 + $10 000 = $110,000. Mr. Brown sold the house $110 000 x 10 / 100 = $11,000 less than its purchased price. Thus, Mr. Brown sold it for $110 000 - $11 000 = $99,000 to his friend. The answer is 99000.
Question: The teacher agrees to order pizza for the class. For every student in the class, she will buy 2 pieces of cheese and 1 piece of onion and they will eat exactly that amount. A large pizza has 18 slices. She orders 6 total pizzas and there are 8 pieces of cheese and 4 pieces of onion leftover. How many students are in the class?
Answer:
Cheese pizzas are 2 / 3 of the pizza's purchased because 2 / (2 + 1) = 2 / 3. She buys 4 cheese pizzas because 6 x (2 / 3) = 4. These give her 72 pieces of cheese pizza because 4 x 18 = 72. The students at 64 pieces of cheese because 72 - 8 = 64. There are 32 students in her class because 64 / 2 = 32. The answer is 32.
