Answer:
Fixed costs:
Rent $9,200
Wages $16,400
Laundry service $7,000
Variable costs:
Soap & Shampoo $3.00
Management fee $1.10
Mixed costs (cleaning):
40 $600
60 $730
90 $960
120 $1,260
140 $1,500
a) variable cost = ($1,500 - $600) / (140 - 40) = $900 / 100 = $9
fixed costs = $600 - ($9 x 40) = $240
b) total fixed costs = $32,840
total variable costs per night = $13.10
c) contribution margin = $90 - $13.10 = $76.90
break even point = $32,840 / $76.90 = 427 nights
sales dollars = $427 x $90 = $38,430
