Lillian Fok is president of Lakefront Manufacturing, a producer of bicycle tires. Fok makes 1,000 tires per day with the following resources: a) Labor productivity per labor hour for these tires = tires/labor hour (round your response to two decimal places). b) Multifactor productivity for these tires = tires/dollar (round your response to four decimal places). c) The percent change in multifactor productivity if Fok can reduce the energy bill by $1,000 per day without cutting production or changing any other inputs =% (enter your response as a percentage rounded to two decimal places). Note: calculate the new multifactor productivity to four decimal places before calculating the percentage change
