[Question]When Pogo, the four-legged martian, walks across the soft Martian soil, it leaves 4 footprints every meter. But Grimzi, the three-legged Plutonian, leaves only 3 footprints in the soft sands of Pluto for every 6 meters it walks. If Pogo travels 6000 meters across the soil of Mars, and Grimzi travels for 6000 meters across the fine sands of Pluto, what is the combined total number of footprints the two creatures will leave on the surfaces of their respective planets?
[Answer]Since Pogo leaves 4 prints per meter, then over 6000 meters it would leave 4 * 6000 = 24,000 footprints on the soils of Mars. Grimzi leaves 3 prints per 6 feet, or 3 / 6 = 0.5 footprints per meter. Then over 6000 meters, Grimzi leaves 0.5 * 6000 = 3000 footprints on the sands of Pluto. In total, the two creatures will leave 24,000 + 3000 = 27,000 footprints. The answer is 27000.
Q: The county fair was hosting a pumpkin contest to see who could grow the biggest pumpkin in pounds. Brad entered his pumpkin with a weight of 54 pounds. Jessica's was half the weight of Brad's. Betty's pumpkin weight 4 times the amount of Jessica's pumpkin. What is the difference between the heaviest and lightest pumpkin in pounds?
A: Jessica's pumpkin weighs half the weight of Brad's 54 - pound pumpkin so 54 / 2 = 27 pounds. Betty's pumpkin weighs 4 times the amount of Jessica's 27 - pound pumpkin so it weighs 4 * 27 = 108. Betty has the heaviest pumpkin at 108 pounds while Jessica's is the lowest at 27 pounds so the difference is 108 - 27 = 81 pounds. The answer is 81.
Question: Valerie needs to put stamps on the envelopes she is about to mail. She has thank you cards for each of her grandmother, uncle and aunt for the birthday presents they sent. She also has to pay the water bill and the electric bill separately. She wants to send three more mail-in rebates than she does bills and she has twice as many job applications as rebates to mail. How many stamps does she need if everything needs 1 stamp except the electric bill, which needs 2?
Answer: Valerie has to send a thank you card to each of 3 people, so she has 3 * 1 = 3 thank you cards to mail. She has 2 bills to mail. She has 3 more rebates than bills, so 3 + 2 = 5 mail - in rebates to mail. She has twice as many job applications as rebates, so she has 2 * 5 = 10 applications to mail. She has 3 + 2 + 5 + 10 = 20 pieces of mail to send. The electric bill needs an extra stamp, so she needs 20 + 1 = 21 stamps. The answer is 21.
[Question]John gets lost on his way home. His normal trip is 150 miles and would take him 3 hours. He ends up driving 50 miles out of the way and has to get back on track. How long did the trip take if he kept the same speed?
[Answer]His speed is 150 / 3 = 50 mph. He was detoured 50 * 2 = 100 miles. So that adds 100 / 50 = 2 hours. So the total trip was 3 + 2 = 5 hours. The answer is 5.
Q: Earl has $90; Fred has $48; Greg has $36. Earl owes Fred $28. Fred owes Greg $32. Greg owes Earl $40. When all debts are paid, how much will Greg and Earl have together in dollars?
A: Earl will have $90 - $28 = $62 after paying off his debt to Fred. Fred will have $48 + $28 = $76 after being paid by Earl. But then Fred will have $76 - $32 = $44 after paying Greg. Greg will have $36 + $32 = $68 after Fred paid him. Then, Greg will have $68 - $40 = $28 after paying off his debt to Earl. Then, Earl will then have $62 + $40 = $102. So together, Greg and Earl will have $28 + $102 = $130. The answer is 130.
Question: Kenny wants to make sure he does more jumping jacks every week than he did the week before. He recorded that last week he did 324 total jumping jacks. On Saturday of this week, he looks at his records and sees that on Sunday he did 34. On Monday he did 20. On Tuesday he skipped a day. On Wednesday he did 123. On Thursday he did 64. On Friday he did 23. How many does he have to do on Saturday to make sure he beats last week's number?
Answer:
He has already done 264 this week because 34 + 20 + 123 + 64 + 23 = 264. If he does 60 he will have done as many as last week because 324 - 264 = 60. He has to do 61 on Saturday because 60 + 1 = 61. The answer is 61.
