Dirth company sells only one product at a regular price of $7.50 per unit. variable expenses are 60% of sales and fixed expenses
makvit [3.9K]

Contribution is the difference between the Sales per unit and the variable cost per unit. When the selling price reduced to $6 per unit,

Contribution per unit = Sales per unit - Variable Cost per unit

Contribution per unit = $6 - ($6*0.6)

Contribution per unit = $2.4 per unit.

Now, the contribution margin ratio = Contribution per unit / Sales per unit

Contribution Margin Ratio = $2.4 / $6

Contribution Margin Ratio = 0.4 or 40%

Contribution Margin ratio when the sales price is $6 per unit is 40%.

Sheffield Corp. purchased machinery for $381,150 on January 1, 2018. It is estimated that it will have a useful life of 10 years
aniked [119]

Answer:

Accumulated depreciation balance on 31 December 2019 = $73,326

Explanation:

Total Cost of the machine = $381,150

Salvage value = $18,150

Therefore value to be depreciated = $381,150 - $18,150 = $363,000

Life of asset = 10 years.

Units to be produced = 290,400

Working hours = 25,000

Under the units of output activity method the asset shall be depreciated based on output, but here the output of machinery is 25,000 hours in its life thus, depreciation shall be charged based on number of hours and not on units.

Therefore accumulated depreciation on December 31 2019 shall be based on total hours of 2018 and 2019

= 2,650 + 2,400 = 5,050 hours

Depreciation = \frac{363,000}{25,000} \times 5,050 = $73,326

Accumulated depreciation balance on 31 December 2019 = $73,326
