A banker earns a $75,000 annual salary, a 2.35% commission on any approved loans for the bank’s business customers, and a fee of $3.75 for each application processed. If the banker has a total of $2.8 million in approved business loans and processes 2,750 applications this year, what are the banker’s earnings rounded to the nearest dollar?

Answers

Answer:

Amount earned = $151,113

Step-by-step explanation:

Here, we are interested in calculating the banker’s earnings rounded to the nearest dollar;

We proceed as follows; we have the following;

1. Annual salary of $75,000

2. 2.35% on approved loans.

Approved loans = 2.8 million

Commission = 2.35/100 * 2.8 million = $65,800

3. $3.75 for each processed loan application

Total = 2750

Amount = 3.75 * 2750 = $10,312.50

Total amount earned is thus;

$75,000 + $65,800 + $10,312.50 = 151,112.5 = 151,113 to the nearest dollar

EXTRA POINTS* how do you graph a fraction? for example slope= 1/2, y-intercept: -2 how do you graph this

Answers

Answer:

Because of the y intercept, you would first plot a point at (0,2). This means that you would put the point when x does not from the origin (middle of the lines) and 2 points up from it. After, for every 2 points going to the right, you go only 1 up on y. This is because the slope is 1/2. I recommend you watch Khan Academy.

Question 1 :In order to convert this equation to Slope-Intercept Form, you must first isolate y.

What is the first step in isolating y?

6x+7y=14

Question 3: Convert to Slope-Intercept Form to graph 3x+5y=10.

Answers

Answer:

Step-by-step explanation:

Add -6x to both sides

6x + 7y + − 6x = 14 + − 6x

7y = − 6x + 14

Divide both sides by 7

7y / 7 = − 6x + 14 / 7

y = − 6 / 7x + 2

Answer

y = −6 / 7x + 2

Graph question: answer would be :  

[tex]y = \frac{-3}{5} x+ 2[/tex]

Place a point on (0,2) and a point on (5, -1)

In order to convert 6x+7y=14 equation to Slope-Intercept Form is use the subtraction property of equality to subtract 6x from both sides of the equation

What is Slope-Intercept?One of the four additional techniques for figuring out any straight line's equation is the slope-intercept form. Typically, straight lines are shown as y = mx+c. The x and y variables are said to have a maximum power of unity by this common straight line equation. As a result, x = x1 and y = y1. Additionally, this demonstrates that only linear equations can be solved using the slope-intercept form. You ought to be able to solve linear equations with two variables. The graph of such equations is a straight line, as you should be aware of. Additionally, you need to be confident in your understanding of the y-intercept, x-intercept, and slope properties of linear equations.

6x + 7y = 14 to rewrite in the form y = mx + b,

make y the subject of the equation 6x + 7y = 14

7y = -6x + 14

divide both sides by 7

y = (-6/7)x + 2

The slope is -6/7 while the intercept is 2.

What is Equation Modelling?

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Given is the sum of three numbers as 26. The second number is twice the first and the third number is 6 more than the second.

Assume that the first number is x.

Then, the second number will be equal to 2x

The third number would be equal to (2x + 6)

Now, theirs sum is equal to 26. Therefore, we can write -

x + 2x + 2x + 6 = 26

5x + 6 = 26

5x = 26 - 6

5x = 20

x = 4

Then,

the second number (y) would be equal to (2 x 4) = 8

the third number (z) would be equal to (2 x 4 + 6) = 14

Therefore, the three numbers are x = 4, y = 8 and z = 14 respectively.

Answers

Answer:

p = 17.5

Step-by-step explanation:

This is the answer because:

1) First, we have to isolate x

2) To isolate x, first -6 from +6 and 48

+6 - 6 = 0

48 - 6 = 42

Equation: 2.4p = 42

3) Now we are left with 2.4p = 42

4) Next, divide 2.4 from 2.4 and 42

2.4/2.4 = 0

42/2.4 = 17.5

5) We are left with

p = 17.5

Therefore, the answer is p = 17.5

Why is preferable to use an acid anhydride for ester formation with an alcohol rather than a carboxylic acid? Select one: Carboxylic acids react with water in an undesired side reaction. Acid anhydrides are generally easier and safer to handle than carboxylic acids. Carboxylic acids change the pH of the solution too much for the reaction to proceed.

New Technology Leads to Bigger CitiesIn the 1800s, the United States was still a very young nation, trying to solidify its identity. The Industrial Revolution began in Great Britain, a fast development of society following the introduction of machines. The United States was slower than Great Britain to fully embrace the changes. Yet key technological developments caused a rapid growth in American urban areas.Better farming methods and tools in the 1800s increased food production. Americans were able to grow enough food for their families as well as to sell. The abundance caused food prices to fall.The expansion of cotton and the growth of textile factories in northern states helped produce the first wave of American industry. More people turned to work in northern factories as a way to support their families. Thousands of immigrants to the United States also settled in or near port cities, looking for work. Even today, the need for work is a common reason people move to urban areas.As a result, cities grew in numbers of people and physical space. As more people and businesses moved in, they needed buildings for living and working. They needed ways to move around the city. We call this process urbanization.In 1820, the United States had only a few cities of 10,000 residents or more. About seven percent of U.S. residents lived in urban areas. The number of cities with more than 10,000 people grew quickly over the next 40 years, especially in the Northeast and Midwest. By 1860, about 20 percent lived in cities. Philadelphia and New York City were the most populated cities in 1860 and would soon reach one million residents.The urbanization of the United States quickened due to technology improvements. Without innovations in food production, the factories could not have grown so quickly. The trend quickened after 1860 and continued throughout the 21st century as well. By 2007, more Americans lived in or near cities than they did in rural areas.Which details are used to support the main fact in the fifth paragraph?
