Prepare a contribution margin analysis report for the year ended December 31. b. At a meeting of the board of directors on January 30, the president, after reviewing the contribution margin analysis report, made the following comment: "It looks as if the price increase of $30 had the effect of increasing sales. However, this was a trade-off since sales volume decreased. Also, variable cost of goods sold per unit increased by $15 more than planned. The variable selling and administrative expenses appear out of control. They increased by $7 per unit more than was planned, which is an increase of over 47% more than was planned. Let's look into these expenses and get them under control. Also, let's consider increasing the sales price to $275 and continue this favorable trade-off between higher price and lower volume." C.
