Answer:
A) $38,650; 48.31%
Explanation:
The computation of the contribution margin and the contribution margin ratio is shown below:
Contribution margin = Service Revenue - Cleaning Supplies Used - wages expense
= $80,000 - $22,000 - $19,350
= $38,650
The variable cost is Cleaning Supplies Used + wages expense
And, the contribution margin ratio equals to
= (Contribution margin ÷ sales) × 100
= ($38,650 ÷ $80,000) × 100
= 48.31%

Answer: The probabilities of winning a contract are

Let the Probability of C winning the contract - P(C) be 'X'
Then,
Probability of B winning the contract - P(B) will be '7X' and
Probability of A winning the contract - P(A) will be 
Since the total of all the probabilities is 1,




So,



Cash flow=net income+non-cash expenses-increase in working capital.
Answer:
a) $3
b) $2
c) 1449
Explanation:
Given:
The cost for a carton of milk = $3
Selling price for a carton of milk = $5
Salvage value = $0 [since When the milk expires, it is thrown out ]3
Mean of historical monthly demand = 1,500
Standard deviation = 200
Now,
a) cost of overstocking = Cost for a carton of milk - Salvage value
= $3 - $0
= $3
cost of under-stocking = Selling price - cost for a carton of milk
= $5 - $3
= $2
b) critical ratio =
or
critical ratio =
or
critical ratio = 0.4
c) optimal quantity of milk cartons = Mean + ( z × standard deviation )
here, z is the z-score for the critical ration of 0.4
we know
z-score(0.4) = -0.253
thus,
optimal quantity of milk cartons = 1,500 + ( -0.253 × 200 )
= 1500 - 50.6
= 1449.4 ≈ 1449 units
