这个题目的原版书题目和答案都贴在下面。是不是错了？看一下我的答案（见附图）。我的解答正确吗？ Fromm’s sensitivity analysis will result in a decrease in the 2015 base case gross profit margin closest to: A. 0.55 percentage points. B. 0.80 percentage points. C. 3.32 percentage points. A is correct. The sensitivity analysis consists of an increase of 20% in the price of an input that constitutes 4% of cost of sales. Change in gross profit margin because of that increase is calculated as the change in cost of sales because of price increase divided by sales: = (Cost of sales × 0.04 × 0.2)/Sales = (105.38 × 0.04 × 0.2)/152.38 = 0.0055
