Janice Davidson, single mother of two in her late 20s, manages an in-store boutique at Lacy's Department Store. She earns $60,000 a year before taxes (her gross income) and pays 20% in taxes. Janice's fixed monthly living expenses are $2,400 with another $1,600 in variable/discretionary living expenses. Janice has $13,000 in emergency savings. Janice has an employer-paid disability benefit through the department store where she works. Lacy's provides its employees a long-term disability insurance benefit that pays 60% of an employee's gross salary up to a maximum of $5,000 a month. Would a policy that pays 40% of her gross salary provide enough income to cover Janice's fixed monthly expenses if she became disabled and couldn't work? If yes, how much could she set aside each month after fixed expenses are paid? If no, how much of a shortfall would she have and how could she cover it?

Answers

Answer:

No, her savings

Step-by-step explanation:

Her monthly income is 5000 (60000/12). She pays $1000 per month (5000x.2) in taxes and has another 2400 in fixed expenses. So her monthly fixed expenses (don’t include 1600 variable) are 3400 (1000+2400). A disability benefit of 40% would pay $2000 per month (5000 x .4). S0 she would be short 1400 per month (2000-3400). She would have to use her $13,000 in savings to make up the difference.

hopefully I interpreted the questions correctly!

a) 40% policy will not cover Janice's fixed monthly expenses.

b) Janice's shortfall is $400.

c) For the shortfall, Janice may resort to emergency funds.

What is a fixed monthly living expense?

A fixed monthly living expense is an expense that does not change from period to period.

Examples of fixed monthly living expenses include:

Mortgage paymentsUtility billsLoan payments.

Data and Calculations:

Annual gross income = $60,000

Annual tax liability = 20% or $12,000 ($60,000 x 20%)

Fixed monthly living expenses = $2,400

Annual fixed living expenses = $28,800 ($2,400 x 12)

Variable discretionary living expenses = $19,200 ($1,600 x 12)

Emergency savings = $13,000

A policy that pays 40% as the disability allowance of gross salary will pay $2,000 ($5,000 x 40%).

Dan bought 5 new baseball trading cards to add to his collection. The next day his dog ate half of his collection. There are now only 46 cards left. How many cards did Dan start with ? show equation

Answers

Answer:

Step-by-step explanation:

Let's say that N is the number of cards.

So the first step is N+5, because dan bought 5 new cards.

Next his dog ate half the collection, so the 2nd piece of the problem is [tex]\frac{N+5}{2}[/tex]

The last step is to now make it an equation. Because there are now 46 cards left, [tex]\frac{N+5}{2}[/tex]=42.

Now solve for N which is N+5=84=> N=79

It can be deduced that the area of the circle will be 26.42 feet.

How to calculate an area of a circle?

It should be noted that the area of a circle is calculated by the formula:

= πr²

In this case, the radius is given as 2.9 feet. Therefore, the area of the circle will be:

= πr²

= 3.142 × 2.9²

= 26.42 feet

In conclusion, the area is 26.42 feet.

The overall distance traveled by a golf ball is tested by hitting the ball with Iron Byron, a mechanical golfer with a swing that is said to emulate the legendary champion, Byron Nelson. Ten randomly selected balls of two brands are tested and the overall distance measured. Assume the data are normally distributed. The data follow:
Brand 1 257 276 260 262 287 271 260 265 283 271
Brand 2 273 281 279 275 271 270 263 267 263 268
1) Is there evidence to show that there is a difference in the mean overall distance of brands? Use alpha = 0.05.
2) Calculate a 95% two-sided confidence interval on the difference in mean overall distance.

Answers

Answer:

1) Since the calculated value of t = -0.241640 does not fall in the critical region so we accept H0 and conclude that there is not enough evidence to show the difference in the mean overall distance of brands.

2) The 95% CI is [-18.587; 1.01242]

Step-by-step explanation:

The given data is

Brand 1 257 276 260 262 287 271 260 265 283 271

Brand 2 273 281 279 275 271 270 263 267 263 268

d² 256 25 361 169 256 1 9 4 400 9 ∑1490

1) Let the hypotheses be

H0: ud= 0 against the claim Ha: ud ≠0

2) The degrees of freedom = n-1= 10-1= 9

3) The significance level is 0.05

4) The test statistic is

t= d`/sd/√n

5) The critical region is ║t║≤ t (0.025,9) = ±2.262

Calculations

6) d`= ∑di/n= -98/10= -9.8

Sd²= ∑(di-d`)²/n-1 = 1/n-1 [∑di²- (∑di)²n]

= 1/9[1490-(-9.8)²/10] =1/9 [1490-9.604]= 164.4884

Sd= 12.825

Therefore

t= d`/ sd/√n

t= -9.8/ 12.825/√10

t= -0.764132/3.16227= -0.241640

7) Conclusion:

2) The confidence interval for the difference of two samples can be calculated by

d ` ± td sd/√n

Putting the values

-9.8 ±2.262* 12.825/√10
