Hello, About 6 weeks ago in the Algebra section there was a problem about nickels, dimes, and quarters. It was something like 100 coins that total $2.99. Is it possible to view this problem again? I was unable to solve it in the past, I would like to try it again.

I looked on the solutions tab and I'm only able to go back 6 weeks, and I'm unable to find the question I'm looking for.

Side note, I think this was a level 3 problem, I am now level 2. Not sure if this relevant but thought it worth mentioning.

Thanks, Jason Davis

TopNewestI have asked this before. If x,y and z are three unknowns for which two independant equations are given and the third condition is that all three are integers,how the third condition can be written in mathematical form and can we solve such equations?

Jason,

You should be able to see it. The problem you are looking for is called

Sum to $2.99it was published seven weeks ago now, week December 24-30. Go back to this week in the solutions tab and click on any of the problems that are visible from those weeks. from there you should be able to move back and forth between that problem and any other problem you looked at that week with in the problem sets(click on the little gray dots above the problem).Log in to reply

Thanks for the replies. The last set of solutions I can view are from 'Six weeks ago December 31 to January 6'. I don't see a way to view any questions previous to that. Thanks, Jason

Jason,

Sorry for the slow response. In general it is possible to see the past solutions for all problems in the problem set that you viewed. If you cannot see it in the solutions tab, then there may be a bug associated with your leveling down. We are looking into it. I'll keep you posted here.
