### Sharmaine's scribepost for Oct.12

For homework Mr.Harbeck gave us a math question about the coin jar. He said to pick 1 purple and 1 any colour besides black.

1. If you share the \$100 with 10 people, how much does each person get?

If you spilt the money, each person gets \$10 each.
Add up all the \$ and you get 100
Add up all the O and you get 10

10 (\$) = 100
10 (O)= 10

100/10 = 10

2. How full is the jar?
I think the jar is 3/4 full. I think that because if you imagine lines dividing the jar in 4 group, the jar isn't even full yet. Another way of saying 3/4 is 75%.

thank for reading my scribepost and don't forget to comment ;)

Coinmath Part 2-
we know the coins add up to 100 dollars in american currency.
1. the combination of usa coins-
1 cent- 80 rolls
5 cent- 10 rolls
10 cent- 4 rolls
25 cent- 2 rolls
Add up to \$100
4000 coins in pennies
400 coins in nickles
200 coins in dimes
80 coins in quarters
Add up to 4680 coins
The combination for canada is
2 roll of pennies= 100 coins= 1.00 dollars
2 roll of nickles= 400 coins= 4.00 dollars
2 roll of dimes= 1000 coins= 10.00 dollars
1 roll of quarters= 1000 coins= 10.00 dollars
1 roll of toonies= 5000 coins= 50.00 dollars
1 roll of lonnies= 2500 coins= 25.00 dollars

equals to \$100 in coins 10 000 coins
How full is the jar?
The jar is 3/4 or 75% full but height of the coins will change in jar if it was canadian. It would change beacause they are about to more coins in the jar loonies and toonies and the size of the coins would change.
