Q: Vincent’s washer broke so he had to go to the laundromat. On Wednesday he washed six loads of clothes. The next day he had time to wash double the number of loads he did the day before. On Friday he had a test and could only manage half of the loads he did on Thursday. On Saturday the laundromat closed at noon and he could only wash a third of the loads of laundry he did on Wednesday. How many loads of laundry had he washed that week?
A: On Thursday he washed 6 * 2 = 12 loads of laundry. On Friday he washed 12 / 2 = 6 loads of laundry. On Saturday he washed 6 / 3 = 2 loads of laundry. In total he washed 6 + 12 + 6 + 2 = 26 loads of laundry. The answer is 26.
Question: Sydney and Conner are having a three day rock collecting contest to see who can have the largest collection after adding to their existing collections. Before they start, Sydney has 837 rocks and Conner has 723. On day one, Sydney collects 4 rocks and Conner collects 8 times as many. On day two Sydney rests and Conner collects 123. On the third day, Sydney collects twice as many as Conner did on the first day. How many does Conner have to collect on day three to make sure he at least ties Sydney?
Answer: On day one Conner collects 32 rocks because 8 x 4 = 32. On day three Sydney collects 64 because 32 x 2 = 64. After three days Sydney has 915 rocks because 837 + 0 + 4 + 64 = 905. Before the third day Conner has 878 because 723 + 32 + 123 = 878. Conner needs to collect 37 on day three to tie Sydney because 905 - 878 = 27. The answer is 27.
[Question]There are 120 cards in a box. If 2/5 of the cards are red, exactly 5/9 of the remainder are black, and the rest are green, calculate the number of green cards in the box?
[Answer]The number of red cards in the box, 2 / 5 of the total number, is 2 / 5 * 120 = 48. The number of cards that are not red is 120 - 48 = 72. If 5 / 9 of the remaining cards are black, then there are 5 / 9 * 72 = 40 black cards in the box. If the remaining cards are green, then there are 72 - 40 = 32 green cards in the box. The answer is 32.
Q: In a certain company, for every customer served, an employee gets as many bonus points, as 20% of the number of customers served. On Monday, Tom served 10 customers per hour for 8 hours. How many bonus points did Tom earn that day?

Question: Lewis found 4 more items on the scavenger hunt than Samantha. Samantha found four times the amount of items than Tanya who was only able to find 4 items. How many items did Lewis find?
