[Question]Paul made two bank transfers of $90 and $60 respectively. A service charge of 2% was added to each transaction. If the second transaction was reversed (without the service charge), what is his account balance now if it was $400 before he made any of the transfers?
[Answer]2% of $90 is (2 / 100) * $90 = $1.8. 2% of $60 is (2 / 100) * $60 = $1.2. The second transaction was reversed without the service charge so only a total of $90 + $1.8 + $1.2 = $93 was deducted from his account. He will have a balance of $400 - $93 = $307. The answer is 307.
Q: There are 10 rows of 15 chairs set up for the award ceremony. The first row is reserved for the awardees while the second and third rows are for the administrators and teachers. The last two rows are then reserved for the parents and the rest of the rows are for the students. If only 4/5 of the seats reserved for the students are occupied, how many vacant seats from the students can be given to the parents?
A: There are 1 + 2 + 2 = 5 rows that are not reserved for the students. Hence, 10 - 5 = 5 rows are reserved for the students. That is equal to 5 x 15 = 75 seats. But only 75 x 4 / 5 = 60 seats are occupied by the students. Therefore, 75 - 60 = 15 seats can be given to the parents. The answer is 15.
Question: The fisherman gets 8 Red snappers and 14 Tunas every day. If a Red snapper costs $3 and a Tuna costs $2, how much does he earn every day?
Answer: The fisherman earns $3 x 8 = $24 per day on Red snappers. He earns $2 x 14 = $28 per day on Tunas. Therefore, the total amount he earns is $24 + $28 = $52. The answer is 52.
[Question]Collin has 25 flowers. Ingrid gives Collin a third of her 33 flowers. If each flower has 4 petals, how many petals does Collin have in total?
[Answer]Ingrid gives Collin 33 / 3 = 11 flowers. Now Collin has 25 + 11 = 36 flowers. Since each flower has 4 petals, Collin has a total of 36 * 4 = 144 flowers. The answer is 144.
Q: Johnny buys 15 packs of colored pencils for his class. Each pack has a red, yellow, and green pencil inside. When he gets home he notices that 3 of the packs have two extra red pencils inside. How many red colored pencils did Johnny buy?
A: Johnny bought 15 packs, and every normal pack has 1 red pencil. He should have 15 * 1 = 15 red pencils. 3 of the packs have 2 extra red colored pencils, so there are 3 * 2 = 6 extra red pencils. In total, Johnny has 15 + 6 = 21 red colored pencils. The answer is 21.
Question: Conner has a dune buggy that he rides in the desert. On flat sand, it can ride at a speed of 60 miles per hour. When traveling on downhill slopes, it can race at 12 miles per hour faster than it can when it is on flat sand. And when riding on an uphill inclined slow, it travels at a speed 18 miles per hour slower than when it is riding on flat sand. If Conner rides his dune buggy one-third of the time on flat sand, one-third of the time on uphill slopes, and one-third of the time on downhill slopes, what is his average speed in miles per hour?
Answer:
12 mph faster than 60mph is 60 + 12 = 72 mph. 18 mph slower than 60 mph is 60 - 18 = 42 mph. If he spends 1 / 3 of the time at each of these three speeds, then he averages (60 + 72 + 42) / 3 = 58 mph. The answer is 58.
