Answer:

Step-by-step explanation:
So, as balloon reaches its maximum height i.e. 11 m , its velocity become 0.
Therefore,
.
It is given that acceleration due to gravity should be taken as ,
.(because it direction is down)
Now it is also given that upward direction is positive and downward direction is negative. So velocity should be negative.
Using equation of motion,
.....eqn 1.
where , displacement = -11 m(because it displace towards down) and 
Putting these values in eqn 1 .


But as we know direction of velocity is downward.
Therefore, 
where negative sign indicates its direction is downward.
Y=8x+12
y=8(32)+12
y=256+12
y=268
y=8(24)+12
y=192+12
y=204
204+268=$472

Hey i think the only mistake i caught was when you put 3 points under the line mark instead of only needing 2.
Possibly another mistake at 3a, Only 2 points (but i could be wrong)
