Hart Company made 3,600 bookshelves using 32,000 board feet of wood costing $332,800. The company's direct materials standards for one bookshelf are 10 board feet of wood at $10.30 per board foot.

Actual Cost Standard Cost Hart Company records standard costs in its accounts and its materials variances in separate accounts when it assigns materials costs to the Work in Process Inventory account. (1) Prepare the journal entry that both charges the direct materials costs to the Work in Process Inventory account and records the materials variances in their proper accounts (2) Assume that Hart's materials variances are the only variances accumulated in the accounting period and that they are immaterial.
