Coin MathFor homework we were asked to choose one purple question and either a blue or red question, excluding black.
The questions I chose were:
How much is $100 American in Canadian dollars more or less?
One hundred dollars in American is less than one hundred dollars in Canadian. It is $103 in Canadian rounded to the nearest hundreds. The converter I used on the internet was: http://www.x-rates.com/calculator.html..
If you share the $100 with 10 people how much does everyone get?
If you share the $100 with 10 people each person would get $10 because you divide $100 by 10 to get $10.
$100/10 = $10

Coin Math Part 2
What we know:
- the value of all the coins added up in the jar is $100 in American currency.
1. Combination of USA coin in the jar
Canadian Coin 1 roll of 1¢, 50¢, 10¢, 25¢
The American calculations would look something like this:
10 rolls of pennies = $5
10 rolls of nickels = $20
5 rolls of dimes = $25
5 rolls of quarters = $50
Total: $100
500 pennies in the jar
400 nickels in the jar
200 dimes in the jar
200 quarters in the jar
Total: 1300 coins altogether
The Canadian calculations would look something like this:
8 rolls of pennies = $4
2 rolls of nickels = $4
2 rolls of dimes = $10
1 roll of quarters = $10
1 roll of loonies = $25
1 roll of toonies = $50
Total: $103 (rounded to the nearest hundreds)
400 pennies
80 nickels
100 dimes
40 quarters
25 loonies
25 toonies
Total: 670
Conclusion:
If you were to put Canadian money in the jar the amount of coins in the jar would decrease. I estimated that there would be 1300 coins in American money and 670 in Canadian money, because of this the jar will have less coins in it if Canadian coins were put in the jar.
2. How full is the jar?
With all the calculations, the amount of Canadian coins in the jar is less than the amount of American coins so the jar would then have less than 3/4 if Canadian coins were to be put in the jar.
