Question 1007577: 1) Nineteen coins are what�s in this cup.
Better believe me �cause that�s what�s up.
There�s no peeking or you�ll never learn.
Wait �til the end when it�s your turn.
A dollar thirty is the total inside.
That�s the truth, I�ve never lied.
So how many nickels and how many dimes?
Figure it out. I�ve got no more rhymes.

Creative problem.
Let n and d be the number of nickels and dimes. Then we have
n + d = 19 and the value equation is
5n + 10d = 130 (we work in cents)
Now multiply the top equation by five and subtract from the second...we get
5n + 10d = 130
-(5n + 5d = 95)
-----------------
5d = 35
d = 7 dimes
n = 12 nickels
