21. 1.Fungsi pendapatan dari suatu pabrik diberikan sebagai berikut :
R = 6 + 350Q ¨C 2Q2
Fungsi produksinya : Q = 3L
Jika jumlah tenaga kerja yang ada 25 orang,berapakah MPRL dan
jelaskan artinya .
Jawab :
R = 6 + 350Q - 2Q? Q = 3L
dR = 350 ¨C 4Q dQ = 3
dQ dL
MPRL = dR = dR . dQ
dL dQ dL
= (350 ¨C 4Q).3
L = 25 Q =3L = 75
dR = (350 ¨C 300).3 = 175
dL
Artinya: Untuk setiap penambahan Tenaga Kerja sebanyak 25 orang akan
menyebabkan penambahan pendapatan sebanyak 175 ,dan sebaliknya
