A company pays 12% commission on sales less than $7,000.00. 14% commission on sales

aleksandrvk [35]

Answer:

<em>The total commission is: $840 + $1,120 + $672 = $2,632</em>

Step-by-step explanation:

<u>Multi-Level Commissions</u>

For sales less than $7,000, a company pays a 12% commission.

For sales between $7,000 and $15,000, the company pays 14%.

For sales greater than $15,000, the company pays 15%.

Let's calculate the commission on sales of $19,480.

For the first $7,000, the commission is:

12*7,000/100 = $840

The remaining sales base is now $19,480-$7,000 = $12,480

For the portion of $8,000 between $7,000 and $15,000, the commission is:

14*$8,000/100 = $1,120

The remaining sales base is now $12,480 - $8,000= $4,480

This portion gets the final 15%:

15*$4,480/100 = $672

The total commission is: $840 + $1,120 + $672 = $2,632

Answer:

-8b + 9 - 5k

Step-by-step explanation:

I am assuming the blue highlighted portion is your answer, and is not a part of the initial question

(-4b + 15 - 7k) - (6 + 4b - 2k)

Combine like terms

-4b - + 4b

Negative + Positive = Negative

-4b - 4b = -8b

15 - 6 = 9

-7k - - 2k

Negative + Negative = Positive

-7k + 2k = -5k

Put them all together:

0b + 9 - 5k

Simplify

-8b + 9 - 5k

I got the same answer as you (just in a different order)

In a lab experiment, 2200 bacteria are placed in a petri dish. The conditions are such that the number of bacteria is able to do

ratelena [41]

The answer would be 5866 because after it multiplied twice it would be at 8800 at that rate it would be gaining 1466.66 an hour so add that to 4400 and u get 5866

PLEASE HELP FOR A BRAINLIEST!!!! Create your own example and explain how to solve Quadratic Equation using Quadratic Formula. Wh

SVETLANKA909090 [29]

Step-by-step explanation:

1. Create your own example and explain how to solve Quadratic Equation using Quadratic Formula.

The quadratic formula is used to solve quadratic equations. It is shown as $x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}$

A quadratic equation is generally shown in the form of $ax^{2} +bx + c = 0$

For example, if you saw the equation $7x^{2} + 3x + 20 = 0$

7 would be $a$ , 3 would be $b$ , and 20 would be $c$ .

To solve the equation above, you would fill in the quadratic formula as such, $x=\dfrac{-3\pm\sqrt{(3)^2-4(7)(20)}}{2(7)}$

Then you could solve for x.

2. What part in the Quadratic Formula is the discriminant?

The discriminant is the equation under the square root on the quadratic formula, $b^{2} - 4ac$

It is tells us whether there are two solutions, one solutions, or no solutions.

3. How do you know the number of solutions based on the value of the discriminant?

To know the number of solutions based off of the value of the discriminant, you need to plug in your values. Using the example quadratic equation, $7x^{2} + 3x + 20 = 0$

We will plug the values into the discriminant.

$3^{2} - 4(7)(20) = -551$

Now, if the discriminant is positive it has two real solutions. If the discriminant is zero the equation has no real-number solutions. And finally, if the discriminant is negative, the equation has one real solution. Because our discriminant is -551, the example equation has one real solution.

Hope this helps! (Please consider Brainliest)
