Number 4 A process currently services an average of 41 customers per day. Observations in recent weeks show that its utilization is about 90 percent, allowing for just a 10 percent capacity cushion. If demand is expected to be 60 percent of the current level in five years and management wants to have a capacity cushion of just 3 percent, what capacity requirement should be planned? The needed capacity requirement is ______________________ customers per day. (Enter your response rounded up to the next whole number.)
