First of all I'll talk about my estimate to how much money is in the jar.
Compared to my estimate the difference from my estimate to the exact amount was a difference of $58.00.
Estimate= $100 American
Answer= $158 American
Difference= $ 58 dollars

How Many Coins Are in the Jar?
(American Jar)
Pennies 1 cent - l,l x 4 =8 -$1
(American Jar)
Money Rolls Value
Pennies 1 cent - l,l x 4 =8 -$1
Nickels 5 cents - l,l x 4 =8 -$4
Dimes 10 cents - l,l x 4 = 8 - $10
Quarters 25 cents - l x 4 = 4 -$10
28 rolls $25 =$100.00
Redone Table
Money - Rolls - Coins in Roll -Total
1 cents - 8 - 50 - 400
5 cents - 8 - 40 - 320
10 cents - 8 - 50 - 400
25 cents - 4 - 40 - 160
There are 1280 totals coins
l = a single roll
Redone Table = means it's more exact
The data shows that there are 1280 coins in the American jar.

(Canadian Jar)
Money - Rolls - Value
1 cent - l,l - $1
5 cents - l,l - $4
10 cents - l,l - $10
25 cents - l,l - $10
$1 - l - $25
$2 - l - $50
= $100.00
Redone Table
Money - Rolls - Coins/Roll -Total
1 cents - l,l - 50 - 100
5 cents - l,l - 40 - 80
10 cents - l,l - 50 - 100
25 cents - l - 40 - 40
$ 1 - l - 25 - 25
$ 2 -l - 25 -25
There are 370 total coins
My conclusion states that there are 370 coins in the Canadian Jar.

This is question is about...
How long will it take to fill the jar, if you put 1 coin in pair day.
The catch is that you start on January. 1 . 2010.
A full jar has about 1707 coins. If you round 1707 to the nearest hundred it would be 1700.You can find out one tenth of the jar by dividing 1700 by 10.One tenth of the jar would have about 170 coins. If you multiply this by 2 to get 2 tenths or 20 percent you get 340. 370 coins would fill up a little bit more than 20 percent or 2 tenths of the jar.
This is what I think the answer would be.
Thanks to Jomari for the help.
p.s. sorry if it looks messy.

Good job Bruce, but I think you should have put a date on when the jar would be fully filled(good job on the math calculations though). I also think that you forgot to state how full the Canadian jar is.
ReplyDeletegood job! very detailed. if you start january 1, 2010 when are you going to stop when the jar is fully filled?
ReplyDeletenicee... its really clear that you putted alot of thought to it.. keep up the good work bruce
