Need help solving the puzzle

Let gift box be x and the Christmas tree be y.

Then:

The equation formed by plugging x in place of gift box and christmas tree will be:

(1) 2x + y + 3 = 16

➛ 2x + y = 13

(2) 3x + y + 1 = 14

➛ 3x + y = 13

Subtracting (2) from (1), And we get:

➛ 3x + y - 2x - y = 0

➛ x = 0

Then, y = 13

We need to find:

• yx + x

= 13 × 0 + 0

= 0

Hence:-

step-by-step explanation: step 3 should really go to step seven, but anyway never mind.

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 %
