Answer: $14220 Favorable
Step-by-step explanation:
Firstly, we will calculate the standard cost to produce 4200 bookshelves. This will be:
= Number of bookshelf × Board feet of wood × Price per board foot
= 4200 × 9 × $9.90
= $374220
Direct material variance will be:
= Standard cost - Actual cost
= $374220 - $360,000
= $14220 Favourable
