Answer:
Output = 4%*3000 * $70 * 3
Output = $25,200
Labor hours productivity = Output / Labor hour
Where Labor hour = 3 * 40 hours = 120 hours
Labor hours productivity = $25,200 / 120 hours
Labor hours productivity = $210 per labor hour
Multi factor productivity for this operation = Output / Multi factor input
Where Multi factor input = 120*$25 + $1,000 + $9,000 = $13,000
Multi factor productivity for this operation = $25,200 / $13,000
Multi factor productivity for this operation = 1.938462
Multi factor productivity for this operation = 1.94
