Solve mentally: Start with 6 dimes and 1 nickel. The difference is $0.55. To get $4.95 as the difference, we have to multiply by the factor $4.95/0.55=9 So there are 54 dimes and 9 nickels. Solve by algebra: N=number of nickels D=6N=number of dimes 0.10D-0.05N=4.95 0.10(6N)-0....

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 ...
