Solve for y: x + 3y = -12

y = -4 - 1/3x

Step-by-step explanation:

x + 3y = -12

-x              -x

3y = -12 - x

divide all by 3, to isolate the y

y = -4 - 1/3x

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 %
