=
$70 – ($15 + $7 + $6)
$42
(b) Break-even point in dollars = 120 lawns X $70 per lawn
= $8,400 per month
EXERCISE 22-3B
(1)
Contribution margin per room
Contribution margin per room
=
=
$120 – ($32 + $40)
$48
(2) Break-even point in dollars = 375 rooms X $120 per room
EXERCISE 22-4B
(a) Contribution margin in dollars: Sales = 600 X $90 = $54,000
Variable costs = $54,000 X .60 = 32,400
Contribution margin $21,600
EXERCISE 22-5B
(a)
(1) Contribution margin ratio is:
$43,200
= 75%
$57,600
(b) At the break-even point fixed costs and contribution margin are equal.
Therefore, the contribution margin at the break-even point would be
$18,000.
EXERCISE 22-6B
(a) Unit contribution margin =
units in sales Breakeven
costs Fixed
Variable cost per unit = Unit selling price – Unit contribution margin
OR
= ($420,000 ÷ $8) X $8.00
Contribution margin ratio = $2.00 ÷ $8.00 = 25%
(b) Fixed costs = Breakeven sales in units X Unit contribution
margin
Fixed costs = Breakeven sales X Contribution margin ratio
Since fixed costs were $105,000 in 2016, the increase in 2017 is $7,500

EXERCISE 22-8B
(a) Sales = Variable cost + Fixed cost + Target net income
(b) Units needed in 2017 =
$540,000 + $162,000*
= 7,800 units
$180 − $90
(c)
$540,000 + $162,000
= 7,000 units, where X = new selling price
X − $90
EXERCISE 22-9B
1. Unit sales price = $350,000 ÷ 5,000 units = $70
Increase selling price to $77, or ($70 X 110%).
Net income = $385,000 – $250,000 – $60,000 = $75,000.

(b) Variable costs = 68% of sales ($1,360,000 ÷ $2,000,000) or $.34 per
bottle ($.50 X 68%). Total fixed costs = $512,000.
(c) Contribution margin ratio = ($.50 – $.34) ÷ $.50

(d) Required sales
PROBLEM 22-3C
(a) Sales were $1,500,000 and variable expenses were $900,000, which
means contribution margin was $600,000 and CM ratio was 40%. Fixed
expenses were $760,000. Therefore, the breakeven point in dollars is:
(b) 1. The effect of this alternative is to increase the selling price per unit
to $28 ($20 X 130%). Total sales become $1,950,000 (75,000 X $26).
Thus, the contribution margin ratio changes to 50% ($900,000 ÷
2. The effects of this alternative are to change total fixed costs to
$590,000 ($760,000 – $170,000) and to change the contribution margin
to .34 [($1,500,000 – $900,000 – $90,000) ÷ $1,500,000]. The new
breakeven point is:
3. The effects of this alternative are: (1) variable and fixed cost of
goods sold become $600,000 each, (2) total variable costs become
$720,000 ($600,000 + $65,000 + $55,000), and (3) total fixed costs
are $940,000 ($600,000 + $275,000 + $65,000). The new breakeven
point is:
X = ($720,000 ÷ $1,500,000)X + $940,000
PROBLEM 22-4C
(a) Current breakeven point: $30X = $13X + $221,000
