Answer:

20 rands/kg

130,000 kg

Step-by-step explanation:

The equilibrium quantity and price are the solution to the system of equations ...

p = 120 -0.7q

p = 3 + 0.2q

Setting these equal, we get ...

0.2q +3 = p = -0.7q +120

0.9q = 117 . . . . . . . add 0.7q-3 to both sides

q = 117/0.9 = 130

p = 3 +0.2·130 = 29

The equilibrium price of maize meal is 29 rands per kg; the market equilibrium quantity is 130,000 kg.

<h3>Answer: Choice C</h3>

Started in Quadrant II and ended in Quadrant IV.

==========================================================

Explanation:

Refer to the diagram below. It shows how the four quadrants are labeled using roman numerals. We start in the upper right corner (aka northeast corner) and work counterclockwise when labeling quadrant I, II, III, and IV in that order.

The green point A is located in quadrant II in the northwest. Meanwhile point B in red is in the southeast quadrant IV.

Therefore, we started in <u>quadrant II</u> and ended in <u>quadrant IV</u> which points us to <u>choice C.</u>
