Answer:
Option B, $45,000, is the right answer.
Step-by-step explanation:
Given actual sales = $450000
Actual units that is sold = 30000 units
Actual selling price = $15 per unit
Planned sales = $540000
Planned units = 45000
Planned selling price = $12 per units.
The difference between actual and planned sales due to unit price factor = change in units × change in price
= (45000 – 30000) × (15 – 12)
= $45000
Thus option B is correct.
