有人知道圈起來的地方的意思是 AgI質量乘 142/233＝新生成的AgCl質量嗎？ 所以這一串式子是原本的AgCl質量再加上後面進行反應新生成的AgCl質量嗎？

4-17. A 0.6407-g sample containing chloride and io- dide ions gave a silver halide precipitate weigh- ing 0.4430 g. This precipitate was then strongly heated in a stream of Cl2 gas to convert the Agi to AgCl; on completion of this treatment, the precipitate weighed 0.3181 g. Calculate the per- centage of chloride and iodide in the sample.

請問21 和 22 題 對於解析看不太懂 不太會計算損益兩平的部分 也不太知道為什麼會用變動成本去除ಥ_ಥ麻煩各位了

Note:變動成本百分比下降,邊際貢獻率一定會上升。 (4) 21. 內獅公司報導銷貨$50,000,固定成本為$30,000,變動成本為$350,000,則損益兩平銷售金額為: (1) $1,000,000 (2) $900,000 (3) $1, 166, 666 (4) $1,100,000 Note:變動成本佔了銷貨收入的35萬 150 萬 = 70%,我們假設銷貨收入為x,則損益兩平時:x- X* 70% – 330,000 = 0 , x = 1,100,000 • to (4) 22. 菁桐咖啡每杯售價為$35,變動成本每杯為 $7,固定成本每月約為 $56,000,如果預期下個月銷貨會成 長 $62,000,請問其凈利預期會增加多少? (1) $36, 000 (2) $33, 600 (3) $41, 600 (4) $49, 600 Note: 變動成本佔了銷貨收入的7135 = 20%,則銷貨成長到62,000 時,淨利會增加:62,000-62,000 x 20% = 49,600,此時因為已超過損益兩平點,多賺的錢不須再拿去支付固定成本了。
