An economy is based on two industrial sectors, agriculture and fabrication. Production of a dollar’s worth of agriculture requires an input of $0.30 from the agriculture sector and $0.20 from the fabrication sector. Production of a dollar’s worth of fabrication requires $0.10 from the agriculture sector and $0.40 from the fabrication sector.
