(b/10) + 10 = (b/5) + 5 b= 2/3) * n + 5 = n - 10 n= 125 * t + 100 * (t-1) = 350 t= (n/2) + (n/4) = 10.5 n=

Step-by-step explanation:

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 %
