Would the jar weigh the same if there was $100 Canadian coins?
No, because Canadian coins have loonies and toonies, and American coins don't. So with the loonies and toonies in the jar, that would probably most likely add on more weight because they are bigger than quarters, dimes, nickles, and pennies.
If you were able to seperate the coins into groups. Which group would have the most coins or highest value?
First I would seperate the coins into groups like, quarters, nickles, dimes, and pennies. I think that the pennies would have more coins because it has less value and doesnt take up as much space and I think that the quarters have the most value because the value of the quarter is more than the rest of the coins in the jar.
How much off the jar is filled with Canadian coins?
With American coins the jar is almost filled up to the top. To me that looks like about 75% or 3/4 of the jar filled. So with Canadian money it would be around 35% or 1/4 of the jar filled. I'm not sure, i'm just guessing, its an estimate.
Could you fill the jar with $100 American and $100 Canadian coins? Why?
No, I think that the coins were over flow or spill over. Because from the question above, by adding the information together - 75% + 35% = 110% That would mean that the jar would over flow because of that 10%. So you can't fill Canadian coins and American coins all in that one jar.
Sorry its so late, but at least I did it ):
