I would do it this way
$780+$225=$1005
$1005/120ft= $8.375
if you have to round up $8.38 per foot
Given t = time and h = height

From the equation.

h is the axis od symmetry
(h, k) is the vertex.
In the equation, h is 1 and k is 16.
So the maximum value is 16 at t = 1.
The ball reaches maximum at 16 and it takes t = 1 to reach the maximum point.
201÷7= 28.71
The answer is 28.71
The screens to blurry, you can’t understand the words
150 and the unknown angle next to it equal 180.
180 - 150= unknown angle
30 degrees= unknown angle
Then the triangle also equals 180 so we add the angles and solve for x
3x + 2x + 30= 180
5x + 30= 180
5x= 150
x= 30
3x= 3(30)= 90 degrees
2x= 2(30)= 60 degrees
