Answer:
The answer is 5300 units.
Step-by-step explanation:
The equation will be exactly lie below if the price is 5$:

Roots of the parabol will be:

In fact that there will be no negative production, The consumer surplus will be 5300 units
Complementary angles add up to 90°
and supplementary angles add up to 180°
Add the two angles together
82+98=180
So the measure of these two angles are supplementary
