Ammorn's Coinmath Part 1 & 2

Our homework was to answer 1 purple question and one red or blue question.

1. Would the jar look the same if it was Canadian money?

No because it will have coins with different sizes and it will be colorful.

2. How much money do the coins add up to?

The coins add up to \$100.

10. 13. 09

1. a) Make a Combination using USA coins:

\$0.01 x 50 = \$0.50 ( pennies )
\$o.05 x 40 = \$2.00 ( nickels )
\$0.10 x 50 = \$5.00 ( dimes )
\$0.25 x 40 = \$10.00 ( quarters )

Im pretty sure you have to use all four types of rolls, so here's my shot at it .

20 rolls of pennies = 1000 coins = \$ 10.00
10 rolls of nickels = 400 coins = \$ 20.00
4 rolls of dimes = 200 coins = \$ 20.00
5 rolls of quarters = 200 coins = \$ 50.00

So all together there is 1800 coins that add up to \$ 100.00. I think that sounds pretty reasonable.

b) Make a combination using Canadian coins:

\$0.01 x 50 = \$0.50 ( pennies )
\$0.05 x 40 = \$2.00 ( nickels )
\$0.10 x 50 = \$5.00 ( dimes )
\$0.25 x 40 = \$10.00 ( quarters )
\$1.00 x 25 = \$25.00 ( loonies )
\$2.00 x 25 = \$50.00 ( toonies )

5 rolls of pennies = 200 coins = \$ 2.00
4 roll of nickels = 160 coins = \$ 8.00
1 roll of dimes = 50 coins = \$ 5.00
1 roll of quarters = 40 coins = \$ 10.00
1 roll of loonies = 25 coins = \$ 25.00
1 roll of toonies = 25 coins = \$ 50.00

All together there would be 500 coins that add up to \$ 100.00

2) How full is the jar ?

Originally, the jar was approximately 3/4 of the way full.

My estimate is that with 500 coins, the jar would be about only 1/2 of the way full in Canadian currency .
