Explanation

(a) (i) Themarginal revenue formula is calculated by dividing the change in totalrevenue by the change in quantity sold. In the case of the question asked, the output (kg) represents the quantity sold.

At output level 15, \(MR = \frac{30 - 0}{15 - 0} = \frac{30}{15} = $2.00\)

At output level 35, \(MR = \frac{70 - 30}{35 - 15} = \frac{40}{20} = $2.00\)

At output level 60, \(MR = \frac{120 - 70}{60 - 35} = \frac{50}{25} = $2.00\)

At output level 85, \(MR = \frac{170 - 120}{85 - 65} = \frac{50}{25} = $2.00\)

(ii) TheMarginal Cost Formulais calculated by dividing the change in Total Cost by the change in quantity sold (or output as regards this question).

At output level 15, \(MC = \frac{45 - 15}{15 - 0} = \frac{30}{15} = $2.00\)

At output level 35, \(MC = \frac{70 - 45}{35 - 15} = \frac{25}{20} = $1.25\)

At output level 60, \(MC = \frac{90 - 70}{60 - 35} = \frac{20}{25} = $0.80\)

At output level 85, \(MC = \frac{105 - 90}{85 - 65} = \frac{15}{25} = $0.60\)

(b)(i) The firm's break-even point is at output level 35.

(ii) The firm makes the highest profit at output level 85.

(iii) The firm attains equilibrium at output level 15.

(c) The firm is operating in perfectly competitive market.
