break even analysis. suppose a certain product sells for a dollars per unit. then the revenue from selling x units of the product is ax dollars if the cost of producting each unit of the product is b dollars and the company has overhead cost of c dollars then the total cost of producing x unit of the product is bx + c dollars. write a programe. ( note revenue is the amount of money received from the sale of the product . the value of a, b and c are called the marginal revenue, marginal cost and fixed cost respectively. the break even point is the value of x for which the revenue equals the total cost. write program that request the marginal revenue. write a program that request the marginal revenue, marginal cost, fixed cost and number of units of the product produced and sold (x) and then displays one of the following three output : profit, loss or break even.

This is what I have so far, but I'm stuck.

If IsNumeric(fixedCost) And IsNumeric(marginalRev) And IsNumeric(marginalCost) And IsNumeric(units) Then
marginalRev = CDbl(txtMargin.Text)
marginalCost = CDbl(txtMarginCost.Text)
fixedCost = CDbl(txtFixedCost.Text)
units = CDbl(txtUnits.Text)
Else
MessageBox.Show("Please enter a number.")
End If
stats = CStr(txtStatus.Text)
stats = marginalRev * marginalCost - (marginalCost * fixedCost)
Select Case stats
Case Is = 0
stats = "Break Even"
Case Is < 0
stats = "Profit"
Case Is > 0
stats = "Loss"
Case Else
stats = "MISTAKE"

End Select
txtStatus.Text = stats
End Sub

To calculate the break-even point and determine whether there is a profit, loss, or break-even, you can use the following program:

```vb
Private Sub CalculateBreakEven()
' Define variables and get user input
Dim marginalRev, marginalCost, fixedCost, units As Double
marginalRev = CDbl(txtMarginalRev.Text)
marginalCost = CDbl(txtMarginalCost.Text)
fixedCost = CDbl(txtFixedCost.Text)
units = CDbl(txtUnits.Text)

' Calculate revenue and total cost
Dim revenue, totalCost As Double
revenue = marginalRev * units
totalCost = (marginalCost * units) + fixedCost

' Determine the status (profit, loss, or break-even)
Dim status As String
If revenue = totalCost Then
status = "Break Even"
ElseIf revenue > totalCost Then
status = "Profit"
Else
status = "Loss"
End If

' Display the result
txtStatus.Text = status
End Sub
```
In this program, we first define variables to store the marginal revenue, marginal cost, fixed cost, and number of units sold. We then get the user input for these values.

Next, we calculate the revenue by multiplying the marginal revenue by the number of units. We also calculate the total cost by multiplying the marginal cost by the number of units and adding the fixed cost.

Finally, we determine the status by comparing the revenue and total cost. If they are equal, it means it's a break-even point. If the revenue is greater than the total cost, it's a profit. If the revenue is less than the total cost, it's a loss. We store the status in the status variable and display it in the txtStatus text box.

Note: Make sure you have the appropriate text boxes (i.e., txtMarginalRev, txtMarginalCost, txtFixedCost, txtUnits, and txtStatus) on your form to display and input the necessary values.
