[Question]A school canteen sells a sandwich at $2, a hamburger at $2, one stick of hotdog at $1, and a can of fruit juice at $2 each can. Selene buys three sandwiches and a can of fruit juice. Tanya buys two hamburgers and two cans of fruit juice. How much do Selene and Tanya spend together?
[Answer]Three sandwiches cost 3 x $2 = $6. So, Selene spends $6 + $2 = $8. Two hamburgers cost 2 x $2 = $4. Two cans of fruit juice cost 2 x $2 = $4. Thus, Tanyah spends $4 + $4 = $8. Therefore, Selene and Tanya spend $8 + $8 = $16. The answer is 16.
Q: Susan walked to the market to buy five dozen peaches. To carry them home, she brought two identically-sized cloth bags and a much smaller knapsack. Into the knapsack she placed half as many peaches as she placed in each of the two cloth bags. How many peaches did she put in the knapsack?
A: 5 dozen peaches is 5 * 12 = 60 peaches. Let "x" be the number of peaches put into the knapsack. Thus, the total number of peaches is x + (2 * x) + (2 * x) = 60. Simplifying the expression, we see that 5 * x = 60. Dividing each side of the equation by 5, we see that x = 12 peaches,. The answer is 12.
Question: Ken likes to bike when it's raining and can cycle 30 miles in 20 minutes during this time. However, when it's snowing Ken can't stand the cold and can only cycle 10 miles in 20 minutes. If it rains 3 times and snows 4 times in one week, how many miles did Ken reach if he cycles 1 hour a day?
Answer: For 1 hour on a rainy day, Ken can cycle 3 * 30 = 90 miles. For 1 hour on a snowy day, Ken can cycle 3 * 10 = 30 miles. On the rainy days this week, Ken cycled 90 * 3 = 270 miles. On the snow days of the week, Ken cycled 30 * 4 = 120 miles. In total, Ken cycled 120 + 270 = 390 miles this week. The answer is 390.
[Question]Ivar owns a stable. He recently has 3 horses and each horse consumes 5 liters of water for drinking and 2 liters for bathing per day. If he added 5 horses, how many liters of water does Ivar need for all the horses for 28 days?
[Answer]The total horse he owns is 5 + 3 = 8. The total liters of water each horse consumes is 5 + 2 = 7. So, the total water all the horses consume every day is 7 x 8 = 56. And the total of liters of water they consume every week is 56 x 7 = 392. Therefore, the total liters of water they consume for the entire month is 392 x 4 = 1568. The answer is 1568.
Q: Two trains left the station at the same time, but took different tracks to their destination. One took a track that was 200 miles long and it went 50 MPH. The other took the other track that was 240 miles long and it went 80 MPH. How much time did it take them on average? (Round to the nearest integer.)
A: The first train took 5 hours because 200 / 40 = 5. The second train took 3 hours because because 240 / 80 = 3. The total time was 8 hours because 5 + 3 = 8. The average time was 4 hours because 8 / 2 = 4. The answer is 4.
Question: To win a brand new Bible at Tom Sawyer's Sunday school, a pupil has to win 10 yellow tickets; each yellow ticket is obtained by trading in 10 red tickets; each red ticket is obtained by trading in 10 blue tickets; and blue tickets are earned by memorizing two Bible verses. But rather than go to all that trouble, Tom Sawyer has traded various toys and treasures of his with his friends until he has gathered 8 yellow, 3 red, and 7 blue tickets. How many more blue tickets would he need to earn to win a new Bible?
Answer:
A red ticket is equal to 10 blue tickets, and a yellow is equal to ten red tickets, so a yellow ticket is also equal to 10 * 10 = 100 blue tickets. It takes 10 yellow tickets to win a Bible, or 10 * 100 = 1000 blue tickets. Tom has 8 yellow tickets, which are worth 8 * 100 = 800 blue tickets. He also has 3 red tickets, which are worth 3 * 10 = 30 blue tickets. Added with his 7 blue tickets, he has 800 + 30 + 7 = 837 blue tickets' worth of tickets. So he still needs to earn 1000 - 837 = 163 blue tickets. The answer is 163.
