Know the answer, but need to show the process:
I have 25 coins in my pocket, totalling $3.65, how many nickels and how many quarters?
for instance, you can have:
1 quarter and 68 nickels, or
2 quarters and 63 nickels, or
3 quarters and 58 nickels, or
as you can see, there are many answers that we can come up with, as easily as choosing how many quarters we want and then working out how many nickels the remainder should be. there must be something else to this question. usually questions like these would also say something like, "there are twice as many nickels as there are quarters" or "when you subtract the number of quarters from the number of nickels you get x" or something
