Job 215 was started and completed during the year. What price would have been charged to the customer if the job required $8,500 in materials and $2,700 in direct labor cost, and the company priced its jobs at 25% above the job's cost according to the accounting system?

Just figure out the total costs and add 25% to it. Except you haven't included any overhead and I'm going to assume that's in another part of the problem somewhere. (I've seen this before so I know it's part of a larger whole.)
