I need some help with these in kinda like a essay form
WINSTONCH [101]

A. The amount (A) at the end of t years of continuous compounding of principal P at rate r will be

... A = Pe^(rt)

For P=1000, r=.02, and t=1, The amount is

... A = $1000e^(.02·1) = $1020.20134

B. The formula for daily compounding is

... A = P(1 + r/365)^(365t)

Using the same values of P, r, t, the amount is

... A = $1000(1 +.02/365)^365 = $1020.20078

Continuous compounding produces a larger result.

The result gets larger the more often compounding occurs. Continuous compounding is the highest possible rate at which compounding can take place, so produces the largest possible result.

C. The balance at the end of the year when interest is compounded n times per year is given by

... A = P(1 + r/n)^n

Each year interest is compounded this way, the amount is multiplied by

... (1 + r/n)^n

When this happens each year for t years, the multiplier has been applied t times. Exponentiation is used to represent the effect of such repeated multiplication, so the balance at the end of t years is

... A = P((1 + r/n)^n)^t = P(1 +r/n)^(nt)

D. (Note the previous answer assumed the existence of this answer.) The same logic as for C above applies for each period that compounding takes place. That is, if compounding occurs n times per year, the interest rate applied for each period is the nominal annual rate r divided by the number of periods n. The multiplier applied to the initial principal amount is

... (1 + r/n)

When than factor is used n times during the year, the multiplier of the initial principal amount is

... (1 + r/n)·(1 + r/n)· ... ·(1 + r/n) . . . where the factor is applied n times.

In more compact notation, this multiplier is

... (1 +r/n)^n

When that multiplier is applied to principal P, the account balance A at the end of the year is ...

... A = P(1 +r/n)^n

The carson family pays $3,252 a year for their cell phones is $3,252 a reasonable answer?
tensa zangetsu [6.8K]

Answer:

Here we will show you how to calculate how much you will make in a year if you make $3252 an hour. Our calculations are based on the following information, but you can change the numbers further down on this page to make it better reflect your situation.

Hourly Pay: $3252

Work hours per week: 40

Work weeks per year: 52

Income Tax Rate: 12%

To calculate how much $3252 an hour is per year, we first calculate weekly pay by multiplying $3252 by 40 hours per week, and then we multiply the product by 52 weeks, like this:

$3252 × 40 hours

= $130,080.00 per week

$130,080.00 × 52 weeks

= $6,764,160.00 per yearNow you know that your gross income per year (income before tax) is $6,764,160.00 if you make $3252 per hour. However, you have to deduct taxes to find your net yearly income (income after tax).

Everyone has to pay 6.2% Social Security Tax and 1.45% Medicare Tax. Furthermore, we assume you will pay about 12% in Federal, State, and Local income taxes. Here is how to calculate your net income (the actual amount you will receive per year):

Social Security Tax

($6,764,160.00 × 6.2)/100

= $419,377.92

Medicare Tax

($6,764,160.00 × 1.45)/100

= $98,080.32

Income Taxes

($6,764,160.00 × 12)/100

= $811,699.20

+ $6,764,160.00 Gross Income

- $419,377.92 Social Security Tax

- $98,080.32 Medicare Tax

- $811,699.20 Federal/State/Local Taxes

= $5,435,002.56 Net IncomeThere you have it. Now you have the answer to "$3252 an hour is how much a year?" If you make $3252 per hour, then your yearly income before taxes is $6,764,160.00 and your yearly income after taxes is $5,435,002.56

We made some assumptions about how much you work and how much taxes you have to pay. You can adjust these assumptions below to match your situation to get the exact amount for your situation.
