An economy is based on two sectors, transportation and manufacturing. Production of a dollar's worth of transportation requires an input of $0.20 from transportation and $0.15 from manufacturing. Production of a dollar's worth of manufacturing requires an input of $0.40 from transportation and $0.30 from manufacturing. If a final demand of $60 million for the transportation and $80 million for the manufacturing is to be satisfied, what must be the output for the manufacturing sector?
