1.
If dollars are included (as in Canada),
$1.45=1 dollar + 5 nickels + 2 dimes
If dollars are excluded,
$1.45=5 quarters + 2 nickels + 1 dime
Try to figure out the probability from these results.

1.
Let N=number of candies of each kind.
N=22.75/(0.35+0.30)=35
So how many candies did Bart buy?

Your answer is right.

I hope you worked out the problem by yourself, in which case you would have followed the same logic where 35 is the number of candies of EACH kind.
