The markup of an MP3 player is $207.20. The markup rate is 60%. What is the cost?
ch4aika [34]

If markup is 60% of the cost, you have

... markup = 0.60×cost

... markup/0.60 = cost

... $207.20/0.60 = cost = $345.33

_____

If markup is 60% of the selling price, the other 40% is the cost. So, the cost is 40/60 = 2/3 of the markup.

... cost = (2/3)×markup = (2/3)×$207.20

... cost = $138.13

_____

Markup can be specified in terms of either selling price or cost. Those are the usual reference values; there could be others. When only the percentage is given, you don't have enough information to work the problem. You need to know what it is a percentage of. (Example problems in your text may tell you the expected interpretation.)

How do you solve this problem: 2y(6 - 1)(6 - 1) = - 200
Lorico [155]

Solve: 2y(6 - 1)(6 - 1) = - 200


Simplify both sides of the equation:


50y = - 200



Divide both sides by 50


50y/50 = -200/50


y = - 4





Answer: y = - 4





Hope that helps!!!!!!! (Answer: y = - 4)

Hello there are 4 questions in this it will look like a lot but it is not and you don't have to answer all of it just look at th
alex41 [277]

Answer:

First one: x = 3, and y = 2

Second: 5

Third: Yes because he will have $37.50

Fourth: The numbers 2.5 and 3 will make it true

Step-by-step explanation:

1. 4(3) + 2(2) + 3 = 12 + 4 + 3 = 19

2. 4x + 2 = 22, 4x = 20, x = 5

3. 2.25y + 7.25z + 11.25, 2.25(2) + 7.25(3) + 11.25 = 4.5 + 21.75 + 11.25 = 37.5

He will get $37.50, which is enough.

4. The numbers 2.5 and 3 will make it true: 2(2.5) + 3 = 5 + 3 = 8, 2(3) + 3 = 6 + 3 = 9, the numbers below it won't make it true.

Please HELP me!! Will choose brainliest (:

Answer:

  yes

Step-by-step explanation:

There are several ways to go at this.

My first choice is to use a graphing calculator. It shows the function has a zero at x=5, so x-5 is a factor.

Another good choice is to use synthetic division (2nd attachment). If the remainder is zero, then x-5 is a factor. It is and it is.

__

You can also evaluate the function at x=5. The remainder theorem tells you that if the value is zero, then x-5 is a factor. Evaluating the polynomial written in Horner form is a lot like synthetic division.

  (((x -4)x -15)x +58)x -40 for x=5 is ... (-10·5 +58)5 -40 = 40-40 = 0

The value of h(5) is zero, so x-5 is a factor of h(x).
