3) A product is marked down 15%; the sale price is $127.46. What was the
original price?

elling price (S.P)  =  (100 - m)% ⋅ Original price (1)

Here,  

S.P  =  127.46,  m  =  15

Substitute 127.46 for S.P and 15 for m in (1).

127.46  =  (100 - 15)% ⋅ Original price

127.46  =  85% ⋅ Original price

127.46  =  0.85 ⋅ Original price

127.46 / 0.85  =  Original price

149.95  =  Original price

So, the original price is $ 149.95.

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 %

not sure but it may be b, as i said i'm not sure.
