Answer:

0.1640 ≤ p ≤0.3532

Explanation:

Sample size (N) = 58 customers

Z-score for 90% interval (Z) = 1.645

The proportion of customers that received some cash back is given by:

p=\frac{15}{58}\\p=0.2586

The confidence interval for the proportion of all depositors who ask for cash back is determined by the following relationship:

p\pm Z*\sqrt{\frac{p*(1-p)}{N}}

Applying the given data:

0.2586\pm 1.645*\sqrt{\frac{0.2586*(1-0.2586)}{58}}\\0.2586\pm0.0946

The upper and lower limits are:

L=0.2586-0.0946\\L =0.1640 \\L=0.2586-0.0946\\L = 0.3532

Using a 90% confidence level, the interval for the proportion (p) is:

0.1640 ≤ p ≤0.3532

Damien Carranza is an nonexempt employee of Verent Enterprises where he is a salesperson, earning a base annual salary of $30,00
Kay [80]

Answer:

Total weekly pay of August =   =  $ 1468.75

Explanation:

Annual salary = $30,000

Monthly Salary = $ 30,000/12=  $ 2500

Salary for 40 hours * ( 4 weeks) = 160 hours = $ 2500

Salary for 1 hour= $ 2500/160=  $ 15.625= $ 15.63

He worked additional 4 hours so pay for four hours is = 4 * 15.63=  $ 62.5

But as he is a non exempt  employee he is entitled to get 1.5 times higher than normal pay for over time so  

he will be paid $ 62.5 * 1.5= $ 93.75 for over time

Commission on Sales = 3 % of $25,000

                                    = $ 750

Weekly pay= $ 2500/4=  $ 625

Total weekly pay of August =  Weekly pay + Commission + Overtime

                                                =  $ 625 +  $ 750 +  $ 93.75

                                                 =  $ 1468.75

LPM’s weighted average cost of capital (WACC) is 13 percent if the firm does not have to issue new common equity; if new common
erica [24]

Answer:

Projects D and E should be purchased.

Explanation:

since the firm's capital structure is 60% debt and 40% equity, it can pursue up to 2 projects. Only projects D, E and F have an internal rate of return higher than the company's WACC, so project G is discarded immediately.

Since projects D and E have a higher IRR, they should be selected.

  • project D: $70,000, IRR = 18%, debt = $42,000, equity = $28,000
  • project E: $85,000, IRR = 15%, debt = $51,000, equity = $34,000
  • total equity invested = $62,000

Splendid Occasions received $2,970 for services to be performed for the next 8 months on March 31 and recorded this transaction
Kay [80]

Answer:

If Splendid Occasions had recorded their service revenue using the other method, how much service revenue would they have recorded for the year?

Ans: $2,970

The ''other method'' in question is the Cash method which recognizes revenue when cash is paid unlike the Accrual method that recognizes it when earned.

Using the Cash method the Service Revenue would be $2,970 because the cash has been received for it.

If Sweet Catering had recorded transactions using the Cash method, how much net income (loss) would they have recorded for the month of May?

= Cash revenues - Cash expense

=  Received cash for meals served to customers - Prepaid rent for three months - Received and paid electricity bill

= 2,530 - 2400 - 60

= $70

If Sweet Catering had recorded transactions using the Accrual method, how much net income (loss) would they have recorded for the month of May?

= Revenue - Expense

= Served a banquet on account + Received cash for meals served to customers - Rent - Electricity - Accrued salary expense - depreciation

= 2,810 + 2,530 - (2,400/3) - 60 - 2,670 - 380

= $1,430
