Hannah's Coin Math

For October 9, we worked in groups

and made questions about this jar that

totals a hundred US dollars.

Question 1:

How long did it take to come up with

all those money?

We do not know for sure, but since it is

made up of pennies, nickels, and dimes, then

it probably took quite a long time to make

a hundred dollars.

Question 2:

If these coins were in Canadian dollars, would

they still sum up to a hundred dollars?

No, because for example, a Canadian dime isn't

worth as much as a US dime.

Sorry for the terrible explanation !


Part 2
How much of the jar Canadian coin?
Okay, so we know that there are 780 American coins and we estimated it to take up 3/4 of the jar or 75% of it. Now if we converted those American coins into Canadian, there would only be 370 of them. 370 in less the half of 780 so it's probably less than 1/4 if the jar. So it's probably 1/8 of it. Or 35%.

Could you fill the jar with $100 American and $100 Canadian? Why ?
No because 75% amd 35% is already over a hundred.
