Question: Era had 5 burgers for her and her 4 friends. She sliced each burger into halves. The first and second friends got 1 and 2 slices, respectively. Then the third and fourth friends got 3 slices each. How many slices of burgers are left for Era?
Answer: There are 5 x 1 / 2 = 10 halves of burgers made from 5 whole burgers. Era's first and second friends got 1 + 2 = 3 slices together. Her third and fourth friends got 3 + 3 = 6 slices together. Era's four friends got 3 + 6 = 9 slices. So, Era is left with 10 - 9 = 1 slice. The answer is 1.
[Question]A couple agreed to split their expenses equally, including the salary of their house help. While doing her job, the house help had an accident; thus, she underwent a medical procedure which cost her $128. The couple decided to pay half of the medical expenses and the other half will be deducted from her $160 salary. If the husband paid for the entire half of the hospital bill, how much does he still need to pay so that they split the expenses for the house help equally?
[Answer]The amount that the couple would cover for the hospital bill is $128 / 2 = $64. The couple's total expenses (salary and hospital bill) is $160 + $64 = $224. So each of them should give $224 / 2 = $112 in total. Since the husband paid the entire half of the hospital bill already ($64), he still needs to pay $112 - $64 = $48. The answer is 48.

Question: Bob enters cycling competitions every single week and hopes to win the 100 dollar grand prize each time. For the first 2 weeks, he managed first place and got 100 dollars each week. He is saving up for a puppy that costs 1000 dollars. What is the minimum number of additional weeks Bob must win first place?
Answer: Two weeks already passed and Bob has 200 dollars. Bob needs 1000 - 200 = 800 more dollars. Bob needs to win the competition for at least 800 / 100 = 8 more weeks. The answer is 8.
[Question]A coach placed 15 tennis balls and 5 soccer balls each into 5 baskets. He gave 5 of his students a short period of time to remove as many balls each from a basket as they could. 3 of them removed 8 balls each and the other 2 removed a certain number of balls each. If a total of 56 balls are still in the baskets, how many balls did the other 2 students each remove?
[Answer]Combining the tennis and soccer balls, there are 15 + 5 = 20 balls in each basket. There are 5 baskets, hence 5 * 20 = 100 balls in total. 3 students removed 8 balls each, they removed 3 * 8 = 24 balls. From the total number of balls, they left 100 - 24 = 76 balls. There are 56 balls left so the other 2 students must have removed a total of 76 - 56 = 20 balls. This means that each of these 2 students removed 20 / 2 = 10 balls. The answer is 10.
[Question]Alyssa took 100 photos on vacation. She wants to put them in a photo album with 30 pages. She can place 3 photos each on the first 10 pages. Then she can place 4 photos each on the next 10 pages. If she wants to put an equal number of photos on each of the remaining pages of the album, how many photos can she place on each page?
[Answer]
There are 3 x 10 = 30 photos in total that can be placed in the first 10 pages. There are 4 x 10 = 40 photos in total that can be placed in the next 10 pages. A total of 10 + 10 = 20 pages of the album have been used. A total of 30 + 40 = 70 photos can be placed on those 20 pages. So there are still 100 - 70 = 30 photos left to be placed on the album. And there are 30 - 20 = 10 pages left in the album. Therefore, 30 / 10 = 3 photos can be placed on each of the pages. The answer is 3.
