103566790 OP : assuming the operating cost remain the same or at least 80% the same, then the reduces in revenue will directly affect on the bottom line , correct me if I'm wrong.

103566790 OP 103966930 : 40% should be the worse case scenario, and Nike can close shop if that happen

103566790 OP : Imagine you earn 100 dollar for sales of 10 apples then less the cost of sales 50 + all the other fixed expense around 40, derriving a net profit of 10 dollar .. What if assuming all the fixed cost and variable cost are same as last quarter but selling price is cheaper by 10% ? your profit will become  0. Of course ,I ignore other factors such as they can reduce the marketing cost or anything else that help increase the bottom line
