Answer:
A
Step-by-step explanation:
The equation of the horizontal line is y = 4 : x ≥ 0
the equation of the oblique line, since it passes through the origin is of the form
y = mx ( m is the slope )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (- 1, - 2 ) ← 2 points on the line
m =
=
= 2
y = 2x : x < 0
20% is same as 0.2
0.2 (x) = 35
--------- ----
0.2 0.2
x = 175
50% is same as 0.5
0.5 (175)
=87.5
The answer is 87.5
I hope this answer helped you.
Have a wonderful day!!
