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,



The break-even point in units using the mathematical equation is 2,000 in units and the unit contribution margin is 80 per unit.
<h3>Break even points in units</h3>
a. Break-even point in unit
Using this formula
Break-even point in unit=Fixed cost/(Selling price-Variable cost)
TC = FC + VC
Sales - TC = Net Income
Sales - TC = 0
Sales - FC - VC = 0
2500(Q)-160,000-170(Q) = 0
80(Q)-160,000 = 0
80(Q)=160,000
Q=160,000/80
Q=2,000 break-even in units
b. Unit contribution margin
Unit contribution margin = Selling price- Variable cost
Unit contribution margin= $250 - $170
Unit contribution margin =$80 per unit
Inconclusion the break-even point in units using the mathematical equation is 2,000 in units and the unit contribution margin is 80 per unit.

To remain efficient and effective, the workflow must follow a certain process flow chart within each department's function.
This is because a process flow chart is a pictorial representation of how each step of a process will be carried out one after the other.
Each step is represented with the actions to be carried out, including the decision.
Usually, a process flow chart is depicted with a shape and line arrow to show the direction from one step to another.
Hence, in this case, it is concluded that to remain efficient and effective, the workflow must follow a certain process flow chart within each department's function.
