The total amount, if $10,000 is invested at an APR of 4% for 10 years is $14000.

When the loan is given to you, then some amount is charged to you for the principal amount and that is called interest.

Given:

$10,000 is invested at an APR of 4% for 10 years.

Calculate the total amount at the end as shown below:

[tex]A = p + p\times r\times t / 100[/tex]

A = 10000 + 10000 × 4 × 10 / 100

A = 10000 + 4000

A = 14000

Similarly, solve all the questions using this formula.

Therefore, the total amount, if $10,000 is invested at an APR of 4% for 10 years is $14000.

The fractions 25/150, 28/154, or 27/62 aren't equivalent.

A fraction is simply a piece of a whole. The number is represented mathematically as a quotient where the numerator and denominator are split. In a simple fraction, the numerator as well as the denominator are both integers.

In order to know if they're equivalent fractions, we can convert them to percentage. This will be:

25/150 × 100 = 16.7%

28/154 × 100 = 18.2%

27/62 × 100 = 43.5%

In this case they're not equivalent.

The value of the logarithm of 0.81 for logarithm properties is equal to - 0.1.

Herein we must use logarithm properties to simplify a given logarithm and solve the resulting expression. The properties to be used in this question are described below:

㏒ (a / b) = ㏒ a - ㏒ b

㏒ aᵇ = b · ㏒ a

First, write the logarithmic equation:

Step-by-step explanation:

The profit that Vaughn would make if he charges $3.80 per bag is $27.20.

The first step is to determine the total pieces of candy that Vaughn plans to sell.

Total pieces of candy = number of pieces in each bag x total number of bags

Total pieces of candy = 24 x 15 = 360

The second step is to determine the total number of bags he has to buy.

Number of bags he is going to buy = total pieces of candy he is going to sell / number of pieces in each bag

Number of bags he is going to buy = 360 / 18 = 20 bags

The third step is to determine the total cost of buying 20 bags

Total cost = number of bags he is going to buy x cost per bag

Total cost = 20 x $3.20

Total cost = $64

The next step is to determine the total revenue from making 24 bags.

Total revenue = price per bag x total number of bags

Total revenue = $3.80 x 24

Total revenue = $91.20

Profit = revenue - cost

$91.20 - $64 = $27.20

The point total possible for the given course is equal to 500.

What is a Percent?

In the question, it is given that you were 6 points shy of a B and the current total points you have is 394.

So, the total number of points you require for a B is calculated as,

[tex]394+6=400[/tex]

So, the value of x is 400.

It is given that you need 80% of the course total for a B.

[tex]\implies p=\frac{80}{100}\\ \implies p=0.8[/tex]

Here, we have to find the base number (b).

We have, x = 80% of b

[tex]\implies x=0.8 \times b\\\implies 400= 0.8 \times b\\\implies x=\frac{400}{0.8}[/tex]

Simplifying, we get

[tex]x=500[/tex]

Therefore, 500 points were possible in the course.

Answer:

range is { - 21, 4 , 14 }

Step-by-step explanation:

the domain gives the value of x , the input

the range is the corresponding values of y, the output

substitute values of x from the domain into the function

x = - 2 : y = - 5(- 2) + 4 = 10 + 4 = 14

x = 0 : y = - 5(0) + 4 = 0 + 4 = 4

x = 5 : y = - 5(5) + 4 = - 25 + 4 = - 21

then range is { - 21, 4 , 14 }

Step-by-step explanation:

Answer:

z = 3.125 * x

Step-by-step explanation:

since y is 80 percent of z, we can represent it in the form of a ratio as 80:100.

Simplify it down: 80:100 = 8:10 = 4:5

therefore x:y = 2:5
and y:z = 4:5

"y" is common in both of these ratios. Therefore we now have to make the value of Y same in both of the ratios. Therefore we find the least common multiple of both the y values which is 5 and 4. It is 20.

Now we make the value of y in both the ratios 20. So we need to multiply 5 in 2:5 by 4. Since we multiplied one of the values by 4 we have to multiply the other one as well (2*4). Now our new ratio for x:y is 8:20. Do the same for the other ratio. the other ratio is 4:5. the y value here is 4. 4 needs to be multiplied by 5 to become 20. Therefore multiply 4 by 5 and multiply 5 by 4. our new ratio for y:z is 20:25

As  you can see both the y values are similar now.

x:y = 8:20

y:x = 20:25

therefore we can now write x:y:z as 8:20:25

that also means that x:z is now 8:25.

Now we know that when x is 8 z is 25. in this case. 8 and 25 are directly proportional.

therefore we can write an equation as
25 = k*8
k = 25/8

k = 3.125

therefore z = 3.125 * x

Compounded quarterly; annual interest rate is 7.875%

========================================================

Explanation:

Let's say we are depositing P = 100 dollars, and we leave it in the account for a timespan of t = 1 year.

This will apply for options A through E.

-------------------

If we go with option A, then we would have n = 1 and r = 0.08

Use the compound interest formula to get the following:

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

A = 100*(1+0.08/1)^(1*1)

A = 108

We'll have $108 dollars in the account at the end of 1 year if we go with option A. The amount of interest only is A-P = 108-100 = 8 dollars.

-------------------

For option B, we have: n = 4 and r = 0.07875

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

A = 100*(1+0.07875/4)^(4*1)

A = 108.110625948487

A = 108.11

So far option B is slightly better since you've earned an extra $0.11, aka 11 cents.

-------------------

For option C, we have: n = 4 and r = 0.07875

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

A = 100*(1+0.0775/12)^(12*1)

A = 108.031299777277

A = 108.03

This amount is less compared to the $108.11 with option B. Therefore, option B is still the best so far.

-------------------

For option D, we have: n = 52 and r = 0.07625

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

A = 100*(1+0.07625/52)^(52*1)

A = 107.917207523206

A = 107.92

This is worse compared to option C.

Option B is still the best so far.

-------------------

For option E, we have: n = 365 and r = 0.075

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

A = 100*(1+0.075/365)^(365*1)

A = 107.787584644

A = 107.79

---------------------

Here's a table comparing the balance after 1 year for options A through E. Those balances all have a starting point of $100 as the deposit.

[tex]\begin{array}{|c|c|} \cline{1-2}\text{Option} & \text{Balance after 1 year}\\\cline{1-2}A & \$108\\\cline{1-2}\boldsymbol{B} & \boldsymbol{\$108.11}\\\cline{1-2}C & \$108.03\\\cline{1-2}D & \$107.92\\\cline{1-2}E & \$107.79\\\cline{1-2}\end{array}[/tex]

Option B is the best choice earning the most ($108.11) if you deposit $100.

There's nothing special about the $100, so feel free to change it to something else to try other starting deposits. You'll find that option B will still provide the highest return.

B
