Answer 1

Answer A

Cost of Grapes = Direct Material

Depreciation = Period Cost

Salary of plant manager = manufacturing overhead

Depreciation = Period Cost

Wages = Direct labor

Answer B

Part a.

Selling Price (A)	$                 10.00
Variable cost per unit (B)	$                   6.00
Contribution per unit (C=A-B)	$                   4.00
Contribution ratio (C/A)	40%

b and c.

Break even Point (in units) = Fixed Cost / Contribution per unit

Break even Point (in $) = Fixed Cost / Contribution Margin ratio

Break Even Point (in units) (54,000 / 4)	13,500
Break Even Point (in $) (54,000 /40%)	$ 135,000

d.

Margin of Safety (in $) = Actual sales (in $) - Break even Point (in $)

= $ 250,000 - $ 135,000

= $ 115,000

Margin of safety ratio = 115,000 / 250,000 = 46%

The ratio shows how the company is operating above break-even point. the managers should try to increase this ratio as much as possible.

e.

Desired sales (in units) = (Fixed Cost + Profit)/ Contribution per unit

= (54,000 + 60,000)/4

= 13,500 units
