Igwe nke anọ nwere ike imepụta 12 awa / ụbọchị * 2 n'arọ / awa = 24 n'arọ / ụbọchị nke ihe. Na ngụkọta igwe niile ga-emepụta 138 kg / ụbọchị + 24 kg / ụbọchị = 162 kg / ụbọchị nke ihe onwunwe. N'ihi ya, ụlọ ọrụ ahụ ga-enweta 162 kg/ụbọchị * $50/kg = $8100/ụbọchị. Ya mere, azịza ya bụ 8100. <eng> The total runtime for the first three machines is 3 machines * 23 hours / day / machine = 69 hours / day. So these machines could produce 69 hours / day * 2 kg / hour = 138 kg / day. The fourth machine could produce 12 hours / day * 2 kg / hour = 24 kg / day of material. In total all the machines would produce 138 kg / day + 24 kg / day = 162 kg / day of material. The factory would therefore earn 162 kg / day * $50 / kg = $8100 / day.
Therefore, the answer is 8100.
