Alvin's Scribepost for October 12, 2009


Today's assignment was to answer one purple question and one question either red or blue.
1. How much money is in half the jar ?
Well since theres $100 dollars in the jar, you divide 100 by 2 which would equal 50.
So there would be $50 in half the jar.
2. What is the biggest coin ?
The biggest coin would be the quarter because the pennie, nickel, and dime are all smaller than the quarter which makes it the biggest coin.
How high are the stack of coins ?
Canadian coins
1 cent = 2mm
2mm x 100 = 200mm
5 cent = 3mm
3mm x 80 = 240mm
10 cent = 1mm
1mm x 100 = 100mm
25 cent = 2mm
2mm x 40 = 80mm
1 dollar = 3mm
3mm x 25 = 75mm
2 dollar = 3mm
3mm x 25 = 75mm
Total Stack = 770mm
American Coins :
1 cent = 2mm
2mm x 500 = 1000mm
5 cent = 3mm
3mm x 400 = 1200mm
10 cent = 1mm
1mm x 250 = 250mm
25 cent = 2mm
2mm x 200 = 400mm
Total stack = 2840 mm
How full is the jar using Canadian coins ?
Well since the jar is 3/4 full with 1350 american coins I think 370 canadian coins would fill 0.75 / 4 of the jar ( 15 % ).
