Rumus untuk menentukan fungsi permintaan dan penawaran adalah sebagai berikut.

Fungsi Permintaan:

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell fraction numerator straight P space minus space straight P subscript 1 over denominator straight P subscript 2 space minus space straight P subscript 1 end fraction space end cell equals cell space fraction numerator straight Q space minus space straight Q subscript 1 over denominator straight Q subscript 2 space minus space straight Q subscript 1 end fraction end cell row cell fraction numerator straight P space minus space 10.000 over denominator 15.000 space minus 10.000 end fraction space end cell equals cell fraction numerator straight Q space minus 10 over denominator 8 space minus space 10 end fraction end cell row cell fraction numerator straight P space minus space 10.000 over denominator 5000 end fraction space end cell equals cell fraction numerator straight Q space minus 10 over denominator negative 2 end fraction end cell row cell negative 2 straight P space plus space 20.000 space end cell equals cell space 5000 straight Q space minus space 50.000 end cell row cell negative 2 straight P space end cell equals cell space 5000 straight Q space minus space 50.000 space minus 20.000 end cell row cell negative 2 straight P space end cell equals cell space 5000 straight Q space minus 70.000 end cell row cell straight P space end cell equals cell space fraction numerator 5000 straight Q space minus 70.000 over denominator negative 2 end fraction end cell row cell straight P subscript straight d space end cell equals cell space minus 2500 straight Q space plus space 35.000 space space end cell end table end style 

Fungsi Penawaran:

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell fraction numerator straight P space minus space straight P subscript 1 over denominator straight P subscript 2 space minus space straight P subscript 1 end fraction space end cell equals cell space fraction numerator straight Q space minus space straight Q subscript 1 over denominator straight Q subscript 2 space minus space straight Q subscript 1 end fraction end cell row cell fraction numerator straight P space minus space 10.000 over denominator 15.000 space minus 10.000 end fraction space end cell equals cell fraction numerator straight Q space minus 8 over denominator 13 space minus space 8 end fraction end cell row cell fraction numerator straight P space minus space 10.000 over denominator 5000 end fraction space end cell equals cell fraction numerator straight Q space minus 8 over denominator 5 end fraction end cell row cell 5 straight P space minus space 50.000 space end cell equals cell space 5000 straight Q space minus space 40.000 end cell row cell 5 straight P space end cell equals cell space 5000 straight Q space plus space 50.000 minus space 40.000 end cell row cell 5 straight P space end cell equals cell space 5000 straight Q space plus space 10.000 end cell row cell straight P space end cell equals cell space fraction numerator 5000 straight Q space plus space 10.000 over denominator 5 end fraction end cell row cell straight P subscript straight s space end cell equals cell space 1000 straight Q space plus space 2.000 space space end cell end table end style 

Berdasarkan penghitungan tersebut, fungsi permintaannya adalah P= - 2500Q + 35.000 dan fungsi penawarannya adalah Ps= 1000Q + 2.000. space
