Respuesta :
1)Variable cost remain constant in per unit whereas Fixed cost remain constant in totality .mixed cost is neither constant in per unit nor in totality .
cost Output Nature
cost of goods sold 240000/4000 or 270000/4500 or 300000/5000 = $ 60 per unit variable
Advertising 21000 at each level of output Fixed
shipping 34000/4000 = 8.5or36000/4500 = 8 neither constant in per unit nor in total Mixed
salaries and commission neither constant in per unit nor in total Mixed
Insurance 6000at each level of output Fixed
Depreciation 15000 at each level of output Fixed
2)change in cost (Highest activity- lowest activity) change in activity [Highest activity -lowest activity] Variable cost per unit Fixed cost at highest activity level [Total cost -variable cost]
Shipping 38000 - 34000 = 4000 5000-4000= 1000 4000/1000 =$ 4 per unit
38000- [5000*4]
38000-20000
18000
salaries and commission 90000-78000= 12000 5000-4000=1000 12000/1000 =$ 12
90000-[5000*12]
90000-60000
30000
Shipping : 4x + 18000
salaries and commission : 12x +30000
3)Income statement ( contribution margin)
sales [5000*100] 500000
less: variable expense [76*5000] (380000)
contribution margin 120000
less: Fixed cost (90000)
net operating income 30000
**selling price = 400000/ 4000 = $ 100 per unit
Variable cost per unit = 60 + 4 shipping expense + 12 salaries and commission = 76
Fixed cost = 21000advertising + 18000 shipping + 30000 salaries and
commission +6000insurance +15000 depreciation
= 90000
