Winkler Furniture manufactures two different types of china cabinets: a French provincial model and a Danish Modern model. Each cabinet produced must go through three departments: carpentry, painting, and finishing. The table below contains all relevant information concerning production times per cabinet produced and production capacities for each operation per day, along with net revenue per unit produced. The firm has a contract with an Indiana distributor to produce a minimum of 300 of each cabinet per week (or 60 cabinets per day). Owner Bob Winkler would like to determine a product mix to maximize his daily revenue.
Formulate as an LP problem and obtain the revenue
| Cabinet Style | Carpentry (hours/cabinet) | Painting (hours/cabinet) | Finishing (hours/cabinet) | Net revenue/cabinet ($) |
| French Provincial | 3 | 1.5 | 0.75 | 28 |
| Danish Modern | 2 | 1 | 0.75 | 25 |
| Department Capacity (hours) | 360 | 200 | 125 |
c. What is the total Revenue at the optimal solution?
d. Bob Winkler wants to add this requirement to his production policy: To produce at least as many French Provencial cabinets as Danish Modern. How many French Provencial and Danish Modern Cabinets should Bob produce?
e. What is the impact on revenue of the solution in part d compared to the result in part c?
Solution for c)
Optimal Solution:
X1 = 60 X2 = 90
Revenue
Revenue =28*60+25*90= $3,930

On January 1, 2021, Farmer Fabrication issued stock options for 360,000 shares to a division manager. The options have an estimated fair value of $8 each. To provide additional incentive for managerial achievement, the options are not exercisable unless divisional revenue increases by 2% in three years. Suppose that Farmer initially estimates that it is not probable the goal will be achieved, but then after one year, Farmer estimates that it is probable that divisional revenue will increase by 2% by the end of 2023.
Required: 1. What is the revised estimate of the total compensation?
2. What action will be taken to account for the options in 2022?
3. Prepare the journal entries to record compensation expense in 2022 and 2023.

A local zoo offers three different memberships:
an individual membership for $99 per year, a dual membership for $175 per year,
and a family membership for $225 per year. The membership director wants a program
that displays the total membership revenue for the year,
as well as the amount of the total revenue contributed by each membership type.
a. enter the input, processing, and output items, as well as the algorithm, in the first column.
b.Desk-check the algorithm twice. For the first desk-check, use 50, 75, and 150
as the numbers of individual, dual, and family memberships sold during the year.
For the second desk-check, use 35, 150, and 265.

Information related to various financial statement elements is provided for three cases:
Case A Tax expense was $341,400. The deferred tax liability had an opening balance of $92,000 and a closing balance of $103,000. Income tax payable declined by $22,400 during the year.
Case B Interest expense was $174,000. Discount amortization was $10,000 during the year. Interest payable had an opening balance of $11,000 and a closing balance of $13,400.
Case C Interest revenue was $87,000. Interest receivable had an opening balance of $14,400 and a closing balance of $8,200.
Required:
For each case, calculate the cash inflow or outflow related to the revenue or expense.

Suppose that a safety group surveyed
1,300
drivers. Among those surveyed,
67%
said that careless or aggressive driving was the biggest threat on the road, and
37
said that cell phone usage by other drivers was the driving behavior that annoyed them the most. Based on these data and assuming that the sample was a simple random sample, construct and interpret a
99%
confidence interval estimate for the true proportion in the population of all drivers who are annoyed by cell phone users.
The confidence interval estimate is (Round to three decimal places as needed. Use ascending order.)
Interpret the confidence interval estimate.
A.There is a
0.99
probability that the sample proportion of drivers who are annoyed by cell phone users is in the interval.
B.There is
99%
confidence that the population proportion of drivers who are annoyed by cell phone users is in the interval.
C.There is a
0.99
probability that the population proportion of drivers who are annoyed by cell phone users is in the interval.
D.There is
99%
confidence that the population proportion of drivers who are annoyed by cell phone users is equal to one of the bounds of the interval
A pharmaceutical company operates retail pharmacies in 10 eastern states. Recently, the company's internal audit department selected a random sample of
300 prescriptions issued throughout the system. The objective of the sampling was to estimate the average dollar value of all prescriptions issued by the company. The data collected were
x overbarxequals=$14.45 and sequals=5.00 Complete parts a and b below.
a. Determine the 90% confidence interval estimate for the true average sales value for prescriptions issued by the company. Interpret the interval estimate.
The 90% confidence interval is (Round to the nearest cent as needed. Use ascending order.)
Interpret the interval. Choose the correct answer below.
A.
The company believes that the true mean prescription amount falls between these two values 90% of the time.
B.
There is a 0.90 probability that the true mean prescription amount is between these two values.
C.
The company believes with 90% confidence that the true mean prescription amount is between these two amounts.
D.
The company believes with 90% confidence that the sample mean prescription amount is between these two amounts.
b. One of its retail outlets recently reported that it had monthly revenue of
$7 485 from 531
prescriptions. Are such results to be expected? Should that retail outlet be audited?Assuming the population mean is at the upper limit of the 90% confidence interval computed in part a, the upper limit of the 90% confidence interval for the expected total monthly revenue for
531
prescriptions would be
$nothing.
Assuming the population mean is at the lower limit of the 90% confidence interval computed in part a, the lower limit of the 90% confidence interval for the expected total monthly revenue for
531
prescriptions would be
Given that this outlet reported sales of
$7, 485 from 531
prescriptions, there is good or no
reason to believe that this is out of line. The retail outlet
should not or should be audited.
