Correct Answer: A. protect agricultural producers

Explanation

When prices are set above equilibrium, it means more suppliers or producers will be willing to sell their goods because of the high prices. This will invariably lead to a surplus of goods in the market resulting in excess supply. This is usually done to protect and encourage production, as producers will be willing to produce and supply to the markets in large quantities when the price is high.

Correct Answer: (a) N150,000

Correct Answer: B. hyperbole

Explanation

(a)

In the diagram above, \(\theta = y\) (vertically opposite angles)

\(\alpha = 180° - 110° = 70°\) (angles on a straight line)

Thus, \(\beta = \theta + \alpha\) (sum of interior opp. angles)

\(\beta = y + 70° ..... (1)\)

\(x + r + \beta = 180° ..... (2)\)

But 2x = r = y

Hence, \(x + 2x + (2x + 70) = 5x + 70 = 180\)

\(5x = 180 - 70 = 110\)

\(x = 22°\)

(b) Let Nx represent the donation collected by the girls. Then, the donation collected by the boys = N(x + 600).

Also, let y represent the average collection, \(x_{g}\), of the girls. Then the average collection, \(x_{b}\), of the boys = N(y + 100).

Thus, \(x_{g} = \frac{x}{12} = y\)

\(x = 12y ... (1)\)

\(x_{b} = \frac{x + 600}{10} = y + 100\)

\(x + 600 = 10(y + 100) .... (2)\)

Substitute 12y for x in (2) :

\(12y + 600 = 10y + 1000\)

\(12y - 10y = 1000 - 600 \)

\(2y = 400 \implies y = 200\)

From (1), \(x = 12y\)

\(\therefore x = 12 \times 200 = N2,400\).

Thus, the girls collected N2,400

The boys collected N2,400 + N600 = N3000

Total = N(2,400 + 3,000) = N5,400

Thus, the girls collected N2,400

The boys collected N2,400 + N600 = N3000

Total = N(2,400 + 3,000) = N5,400
