"Jack has a collection of nickels and quarters. He has a total of 50 coins worth $10.30. How many of each coin does he have?" I got the answer of 39 quarters and 11 nickels by trial and error. Can someone tell me the correct way to set the problem up? Thank you.

sure. If there are n nickels, then there must be 50n quarters, since there are 50 coins in all.
Now, add up the values of the coins:
5n + 25(50n) = 1030
n = 11
