I'm having trouble figuring out parts B and C. I have successfully completed part A.

Kim's Asphalt does driveway and parking lot resurfacing work for large commercial clients as well as small residential clients. An inventory of materials and equipment is on hand at all times so that work can start as quickly as possible. Special equipment is ordered as required. On May 1, the Materials and Equipment Inventory account had a balance of $56,000. The Work-in-Process Inventory account is maintained to record costs of work not yet complete. There were two such jobs on May 1 with the following costs.
