Fungsi konsumsi adalah fungsi yang menunjukan hubungan besarnya konsumsi dengan pendapatan. 

Diketahui:
table attributes columnalign right center left columnspacing 0px end attributes row cell straight C subscript 1 space space end subscript end cell equals cell Rp 1.350.000 comma 00 end cell row cell straight C subscript 2 space space end subscript end cell equals cell Rp 1.550.000 comma 00 end cell row cell straight Y subscript 1 space space end subscript space end cell equals cell Rp 1.500.000 comma 00 end cell row cell straight Y subscript 2 space space end subscript space end cell equals cell Rp 1.750.000 comma 00 end cell end table 

Ditanya:
Berapakah fungsi konsumsi Pak Tonny?

Pembahasan:

table attributes columnalign right center left columnspacing 0px end attributes row cell fraction numerator straight C space minus space straight C subscript 1 over denominator straight C subscript 2 space minus space straight C subscript 1 end fraction space end cell equals cell space fraction numerator straight Y space minus space straight Y subscript 1 over denominator straight Y subscript 2 space minus space straight Y subscript 1 end fraction end cell row cell fraction numerator straight C space minus space Rp 1.350.000 comma 00 over denominator Rp 1.550.000 comma 00 space minus space Rp 1.350.000 comma 00 end fraction space end cell equals cell space fraction numerator straight Y space minus space Rp 1.500.000 comma 00 over denominator Rp 1.750.000 comma 00 space minus space Rp 1.500.000 comma 00 end fraction end cell row cell fraction numerator straight C space minus space Rp 1.350.000 comma 00 over denominator Rp 200.000 comma 00 end fraction space end cell equals cell space fraction numerator straight Y space minus space Rp 1.500.000 comma 00 over denominator Rp 250.000 comma 00 end fraction end cell row cell Rp 250.000 comma 00 space left parenthesis space straight C space minus space Rp 1.350.000 comma 00 space right parenthesis space end cell equals cell space Rp 200.000 comma 00 space left parenthesis space straight Y space minus space Rp 1.500.000 comma 00 right parenthesis end cell row cell Rp 250.000 comma 00 space straight C space minus space Rp 337.500.000.000 comma 00 space end cell equals cell space Rp 200.000 comma 00 space straight Y space minus space Rp 300.000.000.000 comma 00 end cell row cell Rp 250.000 comma 00 space straight C space minus space Rp 37.500.000.000 comma 00 space end cell equals cell space Rp 200.000 comma 00 space straight Y space end cell row blank blank blank row cell straight C space end cell equals cell space fraction numerator Rp 37.500.000.000 comma 00 space plus space Rp 200.000 comma 00 space straight Y space over denominator Rp 250.000 comma 00 end fraction space end cell row cell straight C space end cell equals cell space Rp 150.000 comma 00 space plus space 0 comma 8 space straight Y end cell end table 

Jadi, fungsi konsumsi adalah C = 150.000 + 0,8Y

Jadi, jawaban yang tepat adalah A.undefined
