Nickels = x\nDimes = x + 30\n\n900 = 10(x+30) + 5(x)\n900 = 10x + 300 + 5x\n900 = 15x + 300\n600 = 15x\nx = 40\n\nso, 40 nickels and 70 dimes

119 if I remember my trip to the US Mint correctly.\n\nOdd, that it has 119, why not 120? or 115?

Because the other coin is. You have two coins and logically speaking, one is not a dime but the other is

when it's that large of an amount, every dollar seems to be counted so instead of saying"i won 499999 dollars" it seems to be very big, but again, if you count it in pennies, it's 5 billion small pennies. so would a dollar be considered big? in compairaison to a dime or nickel

Yes, the word "neither" screws up the question.  If neither is a nickel, then there is no nickel.\nBut if "one is not a nickel" then the other could be.

Coins at one time weighed the amount of metal that they contained's value.IE; Gold coins were worth thier weight in Gold, Silver coins (Dimes, Quarters, Half Dollars and Dollars) were worth thier weight in silver, Pennies were copper, 5 Cent coins were Nickel

The two coins are a 50 cent piece and a 5 cent piece...one of them isn't a 50 cent piece, but the other one is!!

if there's a (100 - 100) item, the whole thing equals 0.

Wow, the prices on that website in the first answer are WAY off.  Rediculously off.  $2 for a buffalo nickel?  Many are worth $20, and some hundreds of dollars.   The best way to check a coins value is on ebay.  Like, if you're looking for the value of an 1865 indian cent, you check them on ebay and see that they might average $20.  BUT WAIT, David Lawrence Rare coins (from the link above) will buy them for $2!!!!.   I hope that suckers don't send him their coins.

Pennies aren't copper any more they're mostly Zinc!  And the other coins aren't silver they're mostly made out of nickle.  (which is how the 5 cent piece got called a nickle, but now all the "Silver" coins are nickle.)\n\nAs to why back in the day pennys were made out of copper?  because it was a cheap metal that wouldn't corrode too badly.

You can type in a good description of the coin, it's likely that someone out there has another one just like it.  Otherwise, take it to a coin shop.

In paper (dollars):\n1, 5, 10, 20, 50, 100, 500\n\n\nUsed to be 1000, 10000, and 100000, but I don't know if they're still in circulation.  I think the 100,000 was taken out of circulation years ago.\n\nAlso used to be a 2 dollar bill, but that didn't last long\n\nIn coins (cents): - there are 100 cents in a dollar (for reference)\n1 - penny\n5 - nickel\n10 - dime\n25 - quarter\n50 - half dollar\n\nThen you get into the $1 coins...\n\nHope it helps.  This is the site to the US mint, if you'd like to see the coins.

What math test do you take?  I'm in Algebra 1 and I only remember 1 question.  It's impossible.\n\nSomeone has a total of 100 coins in dimes and quarters.  The total value adds up to $14.05. How many quarters does she have?\n\nA) 27 (I chose this-it's a dollar off)\nB) 40\nC) 56\nD) 79 (I forget-it's way too high)\n\nWell, that's all I have.  Bye bye!\n\nThanks to the guy who solved that.  I won't get a zero now!

If he had NO quarters, then he would have 18 dimes and 22 nickels, worth $2.90.  Every time you replace 1 nickel and 1 dime with 2 quarters, it keeps the coin count right, and the extra nickels right, while the value goes up by (2 * 25 - 10 - 5) = 35 cents.  But to get from $2.90 to $4.05, the total value needs to go up by $1.15 which is NOT an even multiple of $0.35, so there is no solutuion in whole numbers.  One of the figures in the question must be wrong.

There are 20 nickels in a dollar, so we know we are going to have to resort to pennies.\n\nLet's try 20 pennies... Hmm, no single coin makes 80 cents, so that won't work.\n\nOkay let's try 15 pennies.  Now we need 6 coins to make 85 cents:\n1 half-dollar, 1 quarter, 3 nickels... no good only 5 coins\n1 half-dollar, 1 quarter, 1 dime, 1 nickel... no good, 4 coins\n1 half-dollar, 3 dimes, 1 nickel... 5 coins\n1 half-dollar, 2 dimes, 3 nickels -- YES!\n\n3 quarters, 1 dime... bad, 4 coins\n3 quarters, 2 nickels... bad, 5 coins\n\n2 quarters, 3 dimes, 1 nickel -- YES!\n2 quarters, 2 dimes, 3 nickels... bad, 7 coins\n\n1 quarter, 6 dimes... bad\n\nOkay let's try 10 pennies.  Now we need 11 coins to make 90 cents:\n1 half-dollar, 1 quarter, 3 nickels... bad\n3 quarters, 3 nickels... bad\n2 quarters, 8 nickels... bad\n1 quarter, 6 dimes, 1 nickel... bad\n1 quarter, 3 dimes, 7 nickels... eleven coins -- YES!\n9 dimes... bad\n7 dimes, 4 nickels... eleven coins -- YES!\n\nOkay let's try 5 pennies.  Now we need 16 coins to make 95 cents:\n\n1 half-dollar, 9 nickels... bad\n3 quarters, 4 nickels... bad\n2 quarters, 9 nickels... bad\n1 quarter, 14 nickels... bad\n9 dimes, 1 nickel... bad\n3 dimes, 13 nickels... 16 coins -- YES!\n\nSo the answers are:\n1 half-dollar, 2 dimes, 3 nickels, 15 pennies\n2 quarters, 3 dimes, 1 nickel, 15 pennies\n1 quarter, 3 dimes, 7 nickels, 10 pennies\n7 dimes, 4 nickels, 10 pennies\n3 dimes, 13 nickels, 5 pennies\n\nThere are FIVE (5) ways to make one dollar with 21 coins!
