Cornerstone Exercise 9.5
1. Cost of Goods Sold ................................. 25,790
Direct Materials Price Variance .......... 13,450
Direct Labor Efficiency Variance ........ 12,340
Direct Materials Usage Variance .............. 1,100
Direct Labor Rate Variance ...................... 870
Cost of Goods Sold ............................. 1,970
Adjusted Cost of Goods Sold = $1,500,000 – $1,970 + $25,790
= $1,523,820
