Does the subject want to ask, "How much can 2 yuan earn by selling bamboo tube zongzi on a normal day?" 100 yuan. Take an ordinary small booth as an example. Under normal circumstances, you can sell 100 bamboo tube zongzi a day. 2 yuan per zongzi costs 1 yuan (including materials and production costs), so the profit of one day is 100 (sales volume) (price 2 yuan-cost 1 yuan) = 100.
