Answer and Explanation:
a. The computation is shown below:
Material price variance
= Actual Quantity × (Standard Price - Actual Price)
= 14,000 × ($22 - $289,800 ÷ 14,000)
= 14,000 × ($22 - $20.70)
= 14,000 × $1.30
= $18,200 favorable
Material quantity variance
= Standard Price × (Standard Quantity - Actual Quantity)
= $22 × (3,900 units × 2.5 - 14,000 ounces - 4,050 ounces)
= $22 × (9,750 - 9,950)
= $22 × 200
= $4,400 unfavorable
b. Yes the contract should be signed as it is the actual price i.e $20.70 is less than the standard price $22
