Answer: The answer is A. $60,000 increase.
Explanation: 1: The actual units sold multiplied by the budgeted sale price is equal to a total of $440000 (40000 x 11 = $ 440000)
2: The actual units sold multiplied by the actual sale price is equal to $500000 (40,000 x 12.5 = $ 500,000)
3: $500000 - $440000 = $60000 increase by the unit price factor.
