how much do the coins add up to ?
All the coins in the jar add up to $100

Would the jar look the same if the money was Canadian?
It would have less of each coin because Canada has Loonies and Toonies compared to Americans that have bills as dollars. So it would look a lot less if it was all Canadian.

Coin Math part 2

If you started dropping coins into the jar on January 1 , 2010, what day would you finish filling up the jar?

If the jar was filled with all american coins, it would have 1280 coins in it. This filled up 3 quarters of the jar. If you find how much coins can fit in the whole jar it will make this problem easier. So what you do is find how much 1280 divided by 3 multiplied by 4 is.
This gives you about 1707.

So if there is 1707 coins in there jar it would take me approximately 4.79 years to fill the whole jar by putting one coin in it each day. So it would take be around 4 years, so what I'm thinking that it is 79 percent of the year, and that would be around 284 days, I estimate 4 years and 284 days,
That would be October 11, 2014.

How much of the jar is filled with Canadian coins ?

The jar has 370 coins in it. We have found out that 3/4 of the jar is 1280 , so if you divide that by 4 you get 320 , so now we know its more than 1/4 of the jar. So I'm guessing its around 27-30 percent of the whole jar.
