how many burgers would you have to sell before you make back your total costs

你需要賣多少個漢堡妳才能本益平衡不賠錢

the variable unit cost for making one burger is\$0.97

每製作一個漢堡的變動成本是 \$0.97

the unit price your think your might sell the buger for is \$2.79

你認為每個漢堡你能賣 \$2.79

the fixed cost of making burgers for 18 months will be a total \$140000

18 個月製作漢堡的固定成本是 \$140000.

數學很簡單, 答案 = 140000 / (2.79 - 0.97) = 76924 個

這可能兩個字困惑你 variable unit cost 單位變動成本和 fixed cost 固定成本.

fixed cost 指的像店租, 人事費用等, 不會因為你製作漢堡的數量而改變, 故稱為固定成本(fixed cost)

variable unit cost 指的每製造一個漢堡所需的成本, 這部分的成本不是固定的, 跟製作漢堡的數量有關, 所以稱做單位變動成本 (variable unit cost).

the unit price your think your might sell the buger for is \$2.79 應該是:

the unit price you think you might sell the buger for is \$2.79

To 張熙熙,

一個 burger 價格 \$2.79 ; 材料成本 \$0.97

賣一個 burger 賺 2.79-0.97 = \$1.82

請問賣 32,733 個 burgers 賺 \$59,574 怎麼cover \$140,000 的固定成本。

自己的答案也不驗證一下，就說人家 fool !

更正: 是變動成本, 不是材料成本。

You assume X burgers to be sold during that 18 months.

so each burger's fix cost is: 140000/x

now, you add the fixed cost and variable cost together, that shall be the cost of each burger sold within 18 months.

2012-12-01 12:25:53 補充：

if the cost of each burger is equal to the sale price of each burger, then you will break even during that 18 months. Hence, the equation is:

140000/x + 0.97 = 2.79 ==> x = 76923 <== the total amount of burgers need to be sold to break even.

2012-12-01 12:29:25 補充：

"make back" means "break even", that is, the income and cost are equal.

\$140000/\$2,79 = 50179 burges have to sell, but unit cost one burge is \$0.97 = \$48674, then is \$48674 needs to compensate that \$48674/\$2.79 = 17446 burges need to sell, that is 50179 - 17446 = 32733 burges is the total costs back that need to sell.

What is downfloor's saying? Did you see the question about " How many burges would you have to sell before you make back your total costs"? 是你要賣多少個漢堡才能使得總成本賺回來，而且是賺\$140000.那有這麼簡單？fool!
