A is correct. The sensitivity analysis consists of an increase of 20 percent in the price of an input that constitutes 4 percent 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 or 0.55%gross profit margin=gross profit/revenue,为什么答案的算法只用COGS的改变/sales呢?
