Lauren has collected 150 nickles and dimes. She has 70 more nickles than dimes. How many of each does she have?

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.
