The formula for calculating the Confidence Interval is as follows:

Confidence Interval = x +- (z*s)/√N

Where:

x = mean = 10.36

z = taken from standard normal distribution table based on 95% confidence level = 1.96

s = standard deviation = 5.31

N = sample size = 30

Substituting know values on the equation:

Confidence Interval = 10.36 +- ( 1.96 * 5.31) / √30

Confidence Interval = 8.46 and 12.26

Hence the bill of lunch orders ranges from 8.46 to 12.26.

Kangaroo Autos is offering free credit on a new $10,000 car: You pay $1,000 down and then $300 a month for the next 30 months. T
gavmur [86]

Answer:

Kangaroo Auto offers the better deal

If the I go for Kangaroo Autos, then I will save $257.69 in today's term

Explanation:

Here we need to compare the present value of the two options;

Present value is the worth today of an amount or series of amount payable or receivable in the future period.

Where a series of equal amount is receivable or payable in the future it is called an annuity.

One of the payment options includes an annuity. Therefore, we need to work out the present value of the annuity. This is done using the following formula:

Present Value = A ×( 1 - (1+r)^(-n))/r

where A = equal cash flow, r- rate per period, n - no. of periods

A = 300, r- rate per month - 12%/12 = 1% , n= 30

PV = 300 ×(1- (1+0.01)^(-30))/0.01

    = 300 × 25.877

     =7,742.31

Now we can work out he cost of each option  and comapare them in today's Dollar:

Option 1 : Kangaroo Autos

Total cost of option 1 = deposit + PV of annuity

                                  =   1000 + 7,742.31

              cost              = 8,742.31

Option 2: Turtle Motors:

Price =  Car price - Discount

        =   $10,000 - $1000

     cost    =   $9,000

Kangaroo Auto offers a better  deal.

If  I go for Kangaroo Autos, then I will save $257.69 in today's term

Which of the following will increase a company’s current liabilities? You may select more than one answer.
vichka [17]

Answer:

A company purchases inventory on credit.

Explanation:

Current liabilities are those that have to be settled within the fiscal year. The statement above does not specify if the credit has to be paid within the fiscal year, but most likely it has to, because inventories do not usually represent a long-term debt.

So under this sceneario, purchasing inventory on credit would represent an increase in the current liabilities of the firm.

Concepts for Analysis 24-3 (Essay) Presented below are three independent situations.
Helga [31]

Answer:1. Make provision for warranty claims.

2. Disclosure of contingent liability

3. No cost should be recorded.

Explanation:

Warranty is an assurance made by firms to make good any agreed loss that is incurred by the customers in usage of goods and services whiting the period of the warranty. Since an estimation can be made based on firms history of sales a provision has to be made for possible warranty.

Since it's only probably that a loss will be Incurred by the firm by going into the contract and the financial statement has not been issue the firm should made a contingent liability disclosure in the report.

The self insurance is not a contract with a third party, in this vein no cost will be accrued until the loss is actually suffered.
