a) | Hitung |
|
| i | jumlah kos | [2] |
|
| TC = AC x Q Atau TC = TFC + TVC = 15 x 25 = (5 x 25) + (10 x 25) = RM 375.00 = RM 375 |
|
|
|
|
|
| ii | kos tetap | [2] |
|
| TFC = AFC x Q Atau AFC = TC - TVC = 5 x 25 = 375 – 250 = RM 125 = RM 125 |
|
|
|
|
|
| iii | kos berubah purata | [2] |
|
| AVC = TVC ÷ Q Atau AVC = AC – AFC = 250 ÷ 25 = 15 – 5 = RM 10 = RM 10 |
|
|
|
|
|
| iv | kos ketap purata | [2] |
|
| AFC = TFC ÷ Q Atau AVC = AC – AVC = 125 ÷ 25 = 15 – 10 = RM 5 = RM 5 |
|
|
|
|
|
b) | Berapakah keuntungan atau kerugian firma tersebut pada tingkat keseimbangan |
[2] |
| Untung = jumlah hasil – jumlah kos = 625 – 375 = RM 250 |
