Answer:

$467.20

Step-by-step explanation:

Step 1

Let's represent one of the unknown quantities.

We will let:

x= the dealer's cost for the refrigerator (before the markup is added).

Step 2

Let's represent other unknown quantities in terms of xx.

There are no other unknown quantities, so we can skip this step.

Step 3

Now we write an equation in xx that models the conditions.

The dealer's cost plus the 25% markup is the selling price, 584$:\ x + 0.25x = 584x + 0.25x = 584.

Step 4

x + 0.25x = 584  

x(1+0.25)= 584

1.25x=584

<u>125x</u>  <u>= </u>  <u>584</u>

1.25   =   1.25

​

x=467.20

We solve the equation and answer the question.

We find that the dealer's cost before adding markup was $467.20.

Step 5

Finally we check the proposed solution in the original wording of the problem.  The dealer's cost before adding the markup, 467.20$, plus the 25% markup, should equal the final price given in the original wording. 584$. This verifies that the dealer cost before adding the markup was 467.20$. So the answer is $467.20.

Hope this helps you!

Your answer is: $3.15 each.

Here are the steps:

First, I added $2.82 and $1.43. Then, I subtracted the sum ($4.25) from $20. Lastly, I divided the difference($15.75) by five because there were five pineapples. Which gave me the answer: $3.15.

Which two theorems would justify that m∠4 = m∠6, given that m∠5 = m∠6 in the diagram below?
My name is Ann [436]

Answer: D) vertical angles theorem, alternate interior angles theorem

Angle 5 = Angle 6 by the alternate interior angles theorem

Angle 5 = angle 4 by the vertical angles theorem

By the transitive property, we can then say angle 4 = angle 6. These angles are also corresponding angles.

We won't use the angle addition theorem or the right angles theorem.
