Question 51262: In a particular school there are exactly 1000 lockers numbered 1 to 1000. In this school there happen to be exactly 1000 students. One day the math teacher has all of the students line up in the hallway. His instructions are as follows:
"The locker doors are all closed at this time. I would like the first student to go to every locker and open the door. Next, I would like the second student to go to every second locker (#2,#4,#6...)and close the door. Then I would like the third student to go to every third Locker (#3,#6,#9...)and change the current status of the locker door ( if the door is open, close it, if it's closed then open it. Likewise, the fourth student will go to every fourth locker and change the door's status. this pattern will continue until all 1000 students have changed the door status of their appropriate lockers."
after all the students have gone through this process, which of the 1000 lockers will have open doors and which will have closed doors?
The only logical answer I could come up with is locker door #1 will be open and doors #2-1000 will be closed. Is this right?
Thanks so much for any input you can offer.

Question 50910This question is from textbook McDougal Littell Algebra 1
: HI.
I can't figure out this question. I might of gotten it right so far but I'm not sure.
HIKING. You are hiking. the total weight of the backpack and its contents is 13 3/8 pounds. You want to carry no more than 15 pounds. Water bottles weigh 3/4 pound. How many more water bottles can you add to your backpack?
So far I tried 15 + 3/4 x n = 13 3/8
And it said in the back of my book that you subtract 13 3/8 - 13 3/8 +3/4 x n =15 - 13 3/8
So I am not sure what to do on this problem.
thank you very much. I appreciate it. This question is from textbook McDougal Littell Algebra 1

Question 53086: My daughter got this word problem for school and it sounds pretty simple to me but I have tried everything and I am horrible at math so I need a little help before I throw my calculator out the window! Here is it
Linae went shopping for Kou-jong tiles at the local toy shop the other day. The kou-jong tiles were on sale for only 28 cents each.
However, she got it in her head that, for good luck, the total amount of money she must spend must be a number where all of the digits are the same.
With that in mind, what is the minimum number of tiles she must buy?
