Waterways has two major public-park projects to provide with comprehensive irrigation in one of its service locations this month. Job 157 and Job K52 involve 15 acres of landscaped terrain which will require special-order sprinkfer heads to meet the specifications of the project. Using a job cost system to produce these parts, the following events occurred during December. Raw materials were requisitioned from the company's inventory on December 2 for $4,764; on December 8 for $993; and on December 14 for $3,249. In each instance, two-thirds (2/3) of these materials were for J57 and the rest for K52. Six time tickets were turned in for these two projects for a total amount of 18 hours of work. All the workers were paid $16.50 per hour. The time tickets were dated December 3, December 9, and December 15. On each of those days, 6 labor hours were spent on these jobs, two-thirds {2/3) for J57 and the rest for Ks2. The predetermined overhead rate is based on machine hours. The estimated machine hour use for the year is 1,984 hours, and the estimated overhead costs are $742,016 for the year. The machines were used by workers on projects K52 and J57 on December 3,9. and 15. Six machine hours were used for project K52 (2 each day). and 8.5 machine hours were used for project J5) (2.5 the first day and 3 each of the other days). Both of these special orders were completed on December 15 , producing 225 sprinkler heads for 157 and 135 sprinkler heads for K52. (a) Set up the job cost sheets for Job No, 157 and Job No. K52.
