Direct materials and manufacturing labor variances, journal entries. Collegiate Corn Hole is a small business that Zach Morris developed while in college. He began building wooden corn hole game sets for friends, hand painted with college colors and logos. As demand grew, he hired some workers and began to manage the operation. Collegiate Corn Hole maintains two departments: construction and painting. In the construction department, the games require wood and labor. Collegiate Corn Hole has some employees who have been with the company for a very long time and others who are new and inexperienced. Sophomore Corn Hole uses standard costing for the game sets. Kenny expects that a typical set should take 4 hours of labor in the construction department, and the standard wage rate is $10.00 per hour. An average set uses 22 square feet of wood, allowing fora certain amount of scrap. Because of the nature of the wOod, workers must work around the flaws in the materials. Kenny shops around for good deals and expects to pay $4.30 per square foot. Kenny does not store inventory, and buys the wood as he receives an order. For the month of September, Kenny's workers produced 75 corn hole sets using 308 hours and 1,750 square feet of wood. Kenny bought wood for $7,200 (and used the entire quantity), and incurred labor costs of $2,945.
