Megan borrowed $50,000 at 5% simple interest for 6 years. joseph borrowed $60,000 at 4% simple interest for 8 years. using the formula who will have a greater monthly payment, m, and by how much?

Answers

Answer 1

Answer:

Answer:

Megan will pay $78 more than Joseph.

Step-by-step explanation:

Formula: Simple Interest = P x R x T

Megan Info

Borrowed Money (P)=$50,000
Rate of interest (r)=0.05
Time (t) = 6 years

Simple interest paid by Megan = 50,000 x 0.05 x 6 = 15000

Total amount paid in 6 years = 50000 + 15000 = $65,000

Monthly payment by Megan (m) = 65000÷72 = $903

Joseph Info

Borrowed Money (P)=$60,000
Rate of interest (r)=0.04
Time (t) = 8 years

Simple interest paid by Magan = 60,000 x 0.04 x 8 = 19200

Total amount paid in 8 years = 60000 + 19200 = $79,200

Monthly payment by Joseph (m) = 79200÷96 = $825

Now we find Difference of monthly payment

⇒Megan - Joseph

⇒ 903-825

⇒ $78

Thus, Megan will pay $78 more than Joseph.

Notebooks cost $1.20 each. This weekend they will be $.80 What percentage is the sale?

Answers

In the question it is already given that the actual cost of each notebook is $1.20. For the weekend, the notebooks would sold at a discounted rate of $0.80
he
The amount of discount during the weekend = (1.20 - 0.80) dollars
   = 0.40 dollars
So the amount of discount given during the weekend is $0.40
Now we need to find the percentage of discount given during the weekend.
Then
Percentage of discount during the weekend = (0.40/1.20) * 100
   = 0.33 * 100
   = 33
Then the percentage of discount given is 33%.

The sale is 33% off notebooks. This can be found by first subtracting .8 from 1.2

1.2-.8=.4 Now divide .4 by 1.2 to get your answer.

$(.4)/(1.2)$ =.33

.33=33%

You can also solve this mentally because if you know your basic multiplication tables, 3*4=12 and so $(2)/(3)$ of 12 would equal 8.

A store uses the expression –2p + 50 to model the number of backpacks it sells per day, where the price, p, can be anywhere from $9 to $15. Which price gives the store the maximum amount of revenue, and what is the maximum revenue? (Revenue = price mc023-1.jpg number of backpacks.) $9.00 per backpack gives the maximum revenue; the maximum revenue is $32.00. $12.00 per backpack gives the maximum revenue; the maximum revenue is $312.00. $12.50 per backpack gives the maximum revenue; the maximum revenue is $312.50. $15.00 per backpack gives the maximum revenue; the maximum revenue is $20.00.

Answers

Revenue = price * number of backpacks
number of backpacks = -2p + 50

p = 9 ; -2(9) + 50 = -18 + 50 = 32
revenue = 9 * 32 = 288

p = 12 ; -2(12) + 50 = -24 + 50 = 26
revenue = 12 * 26 = 312

p = 12.50 ; -2(12.50) + 50 = -25 + 50 = 25
revenue = 12.50 * 25 = 312.50 GIVES THE MAXIMUM REVENUE

p = 15 ; -2(15) + 50 = -30 + 50 = 20
revenue = 15 * 20 = 300

I need the answer for -3x-3=4x+3

Answers

Answer:

$\huge\boxed{x=-\frac{6}7}$

Step-by-step explanation:

To solve this problem, use the fact that you can perform any operation(with a few exceptions) to both sides of an equation, to isolate the variable.

Simply subtract 3 from both sides to get:

-3x - 3 - 3 = 4x + 3 - 3

-3x - 6 = 4x

Then add 3x to both sides to get:

-3x + 3x - 6 = 4x + 3x

-6 = 7x

Then divide both sides by 7 to get:

-6 / 7 = 7x / 7

-6/7 = x

The first term of an arithmetic sequence is -5, and the tenth term is 13. Find the common difference.1.8

8/9

Answers

Answer:

d = 2

Step-by-step explanation:

The n th term of an arithmetic sequence is

$a_(n)$ = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 5 and a₁₀ = 13, thus

a₁ + 9d = 13, that is

- 5 + 9d = 13 ( add 5 to both sides )

9d = 18 ( divide both sides by 9 )

d = 2

Two variables are correlated with r=0.96 which answer best describes the strength and direction of the association between the variables? A- Strong positive B- Strong negative C- Weak negative D- weak positive

Answers

The description that best describes the strength and direction of the association between the variables is A. Strong positive.

What is a correlation?

A correlation is defined as a causative association between two or more variable, which can be used to make predictions about a given outcome.

The degree and direction of the link between the variables are best described by a strong positive correlation. R = 0.96 indicates that the independent variable raise the dependent variable by 0.96. R correlation ranges from 0 to 1, with 0 indicating the weakest connection and 1 indicating the strongest correlation.

As a result, 0.96 is a strong correlation. The correlation coefficient's minus and positive values indicate the direction of the relationship between the variables.
