The break-even point is measured in units or in sales term to identify the point in a business which is required to cover the total investment costs. The total profit at break-even point is zero.
a)

Answer to Problem 25P
The break-even point quantity for the manual process is 50,000 bags.
Explanation of Solution
Given information:
Manual
Fixed costs= $37,500 / month
Variable costs = $1.75 / bag
Selling price = $2.50 / bag
Mechanized process:
Fixed cost = $75,000 / month
Variable cost = $1.25 / bag
Selling price = $2.50 / bag

e)

Answer to Problem 25P
The monthly profit for the manual process for the sale of 60,000 bags of lettuce per month is $7,500.
Explanation of Solution
Given information:
Manual process:
Fixed costs = $37,500 / month
Variable costs = $1.75 / bag

To determine: The point at which both the process will yield the same amount.
g)

Answer to Problem 25P
The point at which both the process will yield the same amount is 75,000 bags.
Explanation of Solution
Given information:
Manual process:
Fixed costs = $37,500 / month
Variable costs = $1.75 / bag
Selling price = $2.50 / bag
Mechanized process:
Fixed cost = $75,000 / month
Variable cost = $1.25 / bag
Selling price = $2.50 / bag
Formation of equation 1 for manual process:
Formation of equation 2 for mechanized process:
Calculation of the point at which both process yields the same amount:
The point is calculated by substituting all the known values in equation (1) and (2) and equating each other.
Hence, the point at which both the process will yield the same amount is 75,000 bags.
h)
To determine: The range of demand at which the manual process will be preferred over the mechanized process and the range of demand at which the mechanized will be preferred over the manual process.
Introduction:

The indifference point in a business is a point where two different types of alternatives will not have any difference in the output they yield.
h)

Answer to Problem 25P
The manual process will be preferred over the mechanized process for the volume below 75,000 bags. The mechanized process will be preferred over the manual process for the volume above 75,000 bags.

Formation of equation 2 for mechanized process:
Calculation of the point at which both process yields the same amount:
The point is calculated by substituting all the known values in equation (1) and (2) and equating each other.
The fixed costs of both the processes are plotted as shown in the graph. The intersection point in the graph is the point where both process will have no advantage over the other. It is also known as the indifference point. The indifference point is 75, 000 bags.
Hence, the manual process will be preferred over the mechanized process for the volume below 75,000 bags. The mechanized process will be preferred over the manual process for the volume above 75,000 bags.

The following table contains information on the number of RSVP guests for the 145 invitations. Unfortunately, the number of guests does not always correspond to the number of RSVPed guests. Based on her experience, the wedding planner knows it is extremely rare for guests to attend a wedding if they notified that they will not be attending. Therefore, the wedding planner will assume that no one from these 50 invitations will attend. The wedding planner estimates that the each of the 25 guests planning to come solo has a 74% chance of attending alone, a 20% chance of not attending, and a 6% chance of bringing a companion. For each of the 60 RSVPs who plan to bring a companion, there is a 90% chance that they will attend with a companion, a 4% chance of attending…arrow_forward
