Q: Sophie buys five cupcakes at $2 each, six doughnuts at $1 each, four slices of apple pie at $2 per slice, and fifteen cookies at $0.60 each. How much does she spend in all?
A: Five cupcakes cost 5 x $2 = $10. Six doughnuts cost 6 x $1 = $6. Four slices of apple pie cost 4 x $2 = $8. And, fifteen cookies cost 15 x $0.60 = $9. Therefore, Sophie spends $10 + $6 + $8 + $ 9 = $33. The answer is 33.
Question: Mason is trying to download a 880 MB game to his phone. After downloading 310 MB, his Internet connection slows to 3 MB/minute. How many more minutes will it take him to download the game?
Answer: First find how many MB are left to download: 880 MB - 310 MB = 570 MB. Then divide that number by the download speed to find the download time: 570 MB / 3 MB / minute = 190 minutes. The answer is 190.
[Question]Five coworkers were talking during the lunch break. Roger, the oldest one, said that he has the same amount of experience in years as all four of the others combined and that his retirement should come when he accumulates 50 years of experience. Peter said that when he came to the company his daughter was 7 years old, and now she is 19 years old. Tom then said he has twice as many years of experience as Robert. Robert said that he has 4 years of experience less than Peter but 2 more years of experience than Mike. How many more years does Roger have to work before he retires?
[Answer]Peter has 19 – 7 = 12 years of experience. Robert has 12 – 4 = 8 years of experience. Mike has 8 – 2 = 6 years of experience. Tom has 2 * 8 = 16 years of experience. Roger has 12 + 8 + 6 + 16 = 42 years of experience. Roger has to work another 50 – 42 = 8 years before he retires. The answer is 8.
Q: Frank's laundry detergent is double concentrated and will wash 80 loads of laundry. His detergent is usually $25.00 a bottle but they're having a sale. If he buys 2 bottles, both bottles will drop to $20.00 a bottle. How much does he spend, in cents, per load of laundry, if he buys 2 bottles of detergent?
A: If he buys 2 bottles, the price drops to $20.00 per bottle so they cost 2 * 20 = $40.00. He can get 80 loads of laundry per bottle and he bought 2 bottles so that's 80 * 2 = 160 loads of laundry. The detergent cost $40.00 and he will be able to wash 160 loads of laundry so each load costs 40 / 160 = $0.25. The answer is 25.
Question: Taegan goes to a carnival where she wins tickets from each of the 5 carnival games and also finds 5 tickets on the floor. Each ticket is worth $3. In total, she has tickets that total a value of $30. If Taegan won an equal number of tickets from each of the games, how many tickets did she win from each game?
Answer: If tickets are valued at $3 then in total, Taegan has won $30 in total tickets / $3 per ticket = 10 tickets. Some of these tickets were found so only 10 total tickets – 5 found tickets = 5 tickets were won from carnival games. She therefore won 5 tickets / 5 carnival games = 1 ticket from each game. The answer is 1.
Q: Lara is a contestant on a fun game show where she needs to navigate an inflated bouncy house obstacle course. First she needs to carry a backpack full of treasure through the obstacle course and set it down on the other side, which she does in 7 minutes and 23 seconds. Second, she needs to crank open the door to the obstacle course so she can go back through, which takes her 73 seconds. After she gets through the door she traverses the obstacle course again and makes it out faster without the backpack, in 5 minutes and 58 seconds. How many seconds total does it take her to complete the obstacle course?
A:
It takes Lara 7 minutes and 23 seconds to make it through the obstacle course the first time. 7 minutes x 60 seconds per minute = 420 seconds + 23 seconds = 443 seconds to get through the first part of the obstacle course. The second stage of the obstacle course she completes in 73 seconds + 443 seconds = 516 seconds. It takes 5 minutes and 58 seconds for Lara to get through the obstacle course the second time. 5 minutes x 60 seconds per minute = 300 + 58 seconds = 358 seconds. Combined, it takes Lara 516 + 358 seconds = 874 seconds for Lara to run the whole obstacle course. The answer is 874.
