  I think it's 150/2=75 , I may be right, I may be wrong. But I'm not sure.

  Let x = # of dimes and y = # of nickels. y = x + 70 x + y = 150 Substitute x + 70 for y in the second equation. x + x + 70 = 150 2x = 80 x = 40 y = 110

  First, if you have a question, it is much better to put it in as a separate post in <Post a New Question> rather than attaching it to a previous question, where it is more likely to be overlooked. Second, I am not sure what you are asking. To be completely correct, the sentence should be: My sister, Kelly, loves cats. I hope this helps. Thanks for asking.
