Diketahui fungsi produsen P = 1125 – 75P untuk 15 produk yang sama namun
berbeda kualitasnya. Tentukan Average Revenue, Total Revenue dan Marginal
Revenue untuk tiap produk tersebut serta buatlah table kurvanya.
Jawab :
AVERAGE REVENUE DAN TOTAL REVENUE
• Q = 1 unit AR = P, 1125 – (75 x 1) = 1050
TR = P x Q = 1050 x 1 = 1050
• Q = 2 unit AR = P, 1125 – (75 x 2) = 975
TR = P x Q = 975 x 2 = 1950
• Q = 3 unit AR = P, 1125 – (75 x 3) = 900
TR = P x Q = 900 x 3 = 2700
• Q = 4 unit AR = P, 1125 – (75 x 4) = 825
TR = P x Q = 825 x 4 = 3300
• Q = 5 unit AR = P, 1125 – (75 x 5) = 750
TR = P x Q = 750 x 5 = 3750
• Q = 6 unit AR = P, 1125 – (75 x 6) = 675
TR = P x Q = 675 x 6 = 4050
• Q = 7 unit AR = P, 1125 – (75 x 7) = 600
TR = P x Q = 600 x 7 = 4200
• Q = 8 unit AR = P, 1125 – (75 x 8) = 525
TR = P x Q = 525 x 8 = 4200
• Q = 9 unit AR = P, 1125 – (75 x 9) = 450
TR = P x Q = 450 x 9 = 4050
• Q = 10 unit AR = P, 1125 – (75 x 10) = 375
TR = P x Q = 375 x 10 = 3750
• Q = 11 unit AR = P, 1125 – (75 x 11) = 300
TR = P x Q = 300 x 11 = 3300
• Q = 12 unit AR = P, 1125 – (75 x 12) = 225
TR = P x Q = 225 x 12 = 2700
• Q = 13 unit AR = P, 1125 – (75 x 13) = 150
TR = P x Q = 150 x 13 = 1950
• Q = 14 unit AR = P, 1125 – (75 x 14) = 75
TR = P x Q = 75 x 14 = 1050
• Q = 15 unit AR = P, 1125 – (75 x 15) = 0

2. TR = P x Q = 0 x 15 = 0
MARGINAL REVENUE
• MR = ∆TR: ∆Q = (1950 - 1050) : (2 - 1) = 900
• MR = ∆TR: ∆Q = (2700 - 1950) : (3 - 2) = 750
• MR = ∆TR: ∆Q = (3300 - 2700) : (4 - 3) = 600
• MR = ∆TR: ∆Q = (3750 - 3300) : (5 - 4) = 450
• MR = ∆TR: ∆Q = (4050 - 3750) : (6 - 5) = 300
• MR = ∆TR: ∆Q = (4200 - 4050) : (7 - 6) = 150
• MR = ∆TR: ∆Q = (4200 - 4200) : (8 - 7) = 0
• MR = ∆TR: ∆Q = (4050 - 4200) : (9 - 8) = -150

• MR = ∆TR: ∆Q = (1950 - 2700) : (13 - 12) = -750
• MR = ∆TR: ∆Q = (1050 - 1950) : (14 - 13) = -900
• MR = ∆TR: ∆Q = (0 - 1050) : (15 - 14) = -1050
