A company has a factory that is designed so that it is most efficient (average unit cost is minimized) when producing 28,500 units of output each month. However, it has an absolute maximum output capacity of 35,000 units per month and can produce as little as 7,000 units per month without corporate headquarters shifting production to another plant. If the factory produces 22,120 units in October, what is the capacity utilization rate in October for this factory? (Round your answer to 1 decimal place.)
