Tracy has $1.55 in quarters and dimes if she has 3 quarters how many dimes does she have?

$1.55- $0.75= $0.80

one dime equals 10 cents, therefore she has eight (8) dimes and three (3) quarters! :)

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
