Answer: the slope of green line = 
Step-by-step explanation:
We know that,
If two lines are parallel then their slopes(rate of change of y with respect to x) are equal.
Given: The red line and the green line are parallel.
The slope of red line = 
Then, the slope of green line =
[Slopes of two parallel lines are equal]
Hence, the slope of green line = 
If you take the total, and multiply it by the sales tax (.08) then you will get $17.28
(216x.08)
