Answer (A) is correct . Under FIFO, the equivalent-unit materials cost is $2.25 (468000/(32000*0.4+48000*0.9+152000)), and the EWIP contains 43,200 equivalent units of materials. The equivalent-unit conversion cost is $2.92((182880+391160)/(32000*0.8+48000*0.4+152000)), and the EWIP contains 19,200 equivalent units of conversion cost. Consequently, EWIP equals $153,264 [(43,200 ¡Á $2.25) + (19,200 ¡Á $2.92)].Answer (B) is incorrect because The amount of $154,800 is based on a FIFO calculation for materials and a weighted-average calculation for conversion cost. Answer (C) is incorrect because The amount of $155,424 is based on a weighted-average calculation for materials and a FIFO calculation for conversion cost. Answer (D) is incorrect because The amount of $156,960 is based on the unit costs under the weighted-average method.
