Answer:
$150,000 unfavorable variance
Step-by-step explanation:
The budgeted sales volume for the year is 160,000 windows
However,the whole industry sales volume increased to 1,000,000 windows with the company managing to hold on to only 15% of total market sales of 1,000,000 i.e 150,000(1,000,000*15%)
sales activity sale=change in sales volume*standard contribution margin=(160,000-150,000*)$15=$150,000 unfavorable since actual sales were less than forecast sales
