Exercise 8-37, 8-38, 8-39 & 8-40 (Static) (LO 8-2, 3, 5) Skip to question [The following information applies to the questions displayed below.]Pacific Ink had beginning work-in-process inventory of $744,960 on October 1. Of this amount, $304,920 was the cost of direct materials and $440,040 was the cost of conversion. The 48,000 units in the beginning inventory were 30 percent complete with respect to both direct materials and conversion costs. During October, 102,000 units were transferred out and 30,000 remained in ending inventory. The units in ending inventory were 80 percent complete with respect to direct materials and 40 percent complete with respect to conversion costs. Costs incurred during the period amounted to $2,343,600 for direct materials and $3,027,840 for conversion. Exercise 8-37 (Static) Compute Costs per Equivalent Unit: Weighted-Average Method (LO 8-3) Required: a. Compute the equivalent units for the materials and conversion cost calculations. b.…
3. Figure 5.11 details the process flow for two types of custom-ers who enter Barbara’s Boutique shop for customized dressalterations. After step T1, Type A customers proceed to step T2and then to any of the three workstations at T3, followed bysteps T4 and T7. After step T1, Type B customers proceed tostep T5 and then steps T6 and T7. The numbers in parenthe-ses are the minutes it takes to process a customer.a. What is the capacity of Barbara’s shop in terms of thenumbers of Type A customers who can be served in anhour? Assume no customers are waiting at steps T1 or T7.b. If 30 percent of the customers are Type A customers and70 percent are Type B customers, what is the averagecapacity of Barbara’s shop in customers per hour? c. Assuming that the arrival rate is greater than five custom-ers per hour, when would you expect Type A customers toexperience waiting lines, assuming no Type B customersin the shop? Where would the Type B customers have towait, assuming no Type A customers?
