Q: When Patrick, Manu, and Amy participate in a race they realize that Patrick finishes the race in 60 seconds. Manu took 12 more seconds to finish the race. If Amy is twice as fast as Manu, how long did it take her to finish the race?
A: The time it took Manu to complete the race is 60 + 12 = 72 seconds. If Amy is twice as fast as Manu, then she takes half the time Manu did to finish the race, so Amy took 1 / 2 * 72 = 36 seconds. The answer is 36.
Question: Alfred likes to save $1,000.00 over 12 months for his Christmas shopping. He has $100.00 left over from last year's holiday to put towards this year's goal. How much money does Alfred now need to save each month in order to reach his goal in 12 months?
Answer: He wants to save $1,000.00 and he has $100.00 left over so he still needs to save 1000 - 100 = $900.00. He wants to save $900.00 over 12 months so that means he needs to save 900 / 12 = $75.00 per month. The answer is 75.
[Question]Merry had 50 boxes of apples on Saturday and 25 boxes on Sunday. There were 10 apples in each box. If she sold a total of 720 apples on Saturday and Sunday, how many boxes of apples are left?
[Answer]Merry had a total of 50 + 25 = 75 boxes of apples. These 75 boxes is equal to 75 x 10 = 750 apples. There were 750 - 720 = 30 apples left. Thus, 30 / 10 = 3 boxes of apples are left. The answer is 3.
Q: A tank with a capacity of 8000 gallons is 3/4 full. Daxton empty's the tank by 40% of the total volume of water in the tank to water his vegetable farm. He then fills the tank with 30% of the volume of water remaining in the tank. Calculate the final volume of water in the tank.
A: The volume of water that is in the tank initially is 3 / 4 * 8000 = 6000 gallons. When Daxton empties 40% of the water, he pumps out 40 / 100 * 6000 = 2400 gallons of water. The total volume of water remaining in the tank is 6000 - 2400 = 3600 gallons. Daxton then fills the tank with 30 / 100 * 3600 = 1080 gallons of water. The final volume of water in the tank is 3600 + 1080 = 4680 gallons. The answer is 4680.
Question: Milly's babysitter charges $16/hour. Milly is considering switching to a new babysitter who charges $12/hour, but also charges an extra $3 for each time the kids scream at her. If Milly usually hires the babysitter for 6 hours, and her kids usually scream twice per babysitting gig, how much less will the new babysitter cost?
Answer: First figure out how much the first babysitter costs by multiplying her hourly rate by the number of hours she works: $16 / hour * 6 hours = $96. Then use the same method to figure out how much the second babysitter charges before any screaming: $12 / hour * 6 hours = $72. Then figure out how much the babysitter charges for two screams: 2 screams * $3 / scream = $6. Finally, subtract the second babysitter's two charges from the first babysitter's total charge to find the difference: $96 - $72 - $6 = $18. The answer is 18.
Q: William read 6 books last month and Brad read thrice as many books as William did. This month, in an effort to catch up, Williams read twice as much as Brad, who read 8 books. Who has read more across the two months, and by how much?
A:
Last month Brad read thrice 6 books for a total of 3 * 6 = 18 books. This month Williams read twice 8 books for a total of 2 * 8 = 16 books. Across the 2 months Brad has read 18 + 8 = 26 books. Across the 2 months William has read 6 + 16 = 22 books. Brad has read 26 - 22 = 4 more books. The answer is 4.
