Is number 30 <br> -r=-23?

1. Mrs. Nelson wants to buy a wireless speaker for her son. She has narrowed down her choice to two stores:

Oksi-84 [34.3K]

a) Mrs. Nelson will pay $45 for the speaker at Kohl's.

b) Mrs. Nelson would pay $43.70 for the speaker at Target.

c) Mrs. Nelson would get the best deal from Target's.

Step-by-step explanation:

Selling price at Kohl = $60.00

Discount coupon = 25%

Purchase price of Target = $38.00

Mark up = 15%

a.) How much would Mrs. Nelson pay for the speaker at Kohl’s?

Discount = 25% of selling price

Discount amount = $\frac{25}{100}*60=\frac{1500}{100}$

Discount amount = $15

Cost after discount = Selling price - Discount amount

Cost after discount = 60-15 = $45

Mrs. Nelson will pay $45 for the speaker at Kohl's.

b.) How much would Mrs. Nelson pay for this speaker at Target?

Mark up = 15% of purchase price

Mark up amount = $\frac{15}{100}*38=\frac{570}{100}$

Mark up amount = $5.70

Price after mark up = Purchase price + Mark up amount

Price after mark up = 38.00+5.70 = $43.70

Mrs. Nelson would pay $43.70 for the speaker at Target.

c.) Which store would Mrs. Nelson get the best deal and by how much?

Difference between prices = 45-43.70 = $1.30

Mrs. Nelson will save $15 on Kohl's and she will get the speaker at $43.70 at Target's, therefore, she would save $1.30 more if she buys speaker from Target's.

Mrs. Nelson would get the best deal from Target's.

25.7 is what percent of 141? Show wrk

Vilka [71]

Divide 25.7 by 141.

$\dfrac{25.7}{141} \approx 0.1822$

Now, multiply that with 100 percent to get the percentage.

$0.1822 \times 100 \%=18.22 \%$

18.22% is your answer! If the question wants you to round it to the nearest percent, the answer will be 18%.

I have one selected but I don't know if it's right? can someone tell me the right answer so I can understand what I did wrong?

kozerog [31]

Answer:

It's y = 3

Step-by-step explanation:

Reason why it's not x = 3 is because x is on the left to right or horizontal plane, therefore it would be y because y is on the vertical axis. If using x, it would be a vertical line on x while using y would create a horizontal line.

R/3=7 one-step equations: integers

gladu [14]

Answer:

r = 21

Step-by-step explanation:

The "one step" is to undo the division by 3. To undo that division, you multiply both sides of the equation by 3. this gives you ...

r·(3/3) = 7·3

r = 21

_____

The basic idea of any equation solution process is to "undo" what has been done to the variable. This is where the multiplication and addition identity elements come into play.

In this problem, the variable is multiplied by 1/3. The number that you multiply this by to get the identity element for multiplication (1) is the inverse of this fraction: 3/1, or 3. That is, 3 × 1/3 = 3/3 = 1. When 1 multiplies r, the result is just r, which is what you're trying to get to.

The rules of equality tell you that whatever you do to one side of an equation, you must also do to the other side. If you multiply r/3 by 3 on the left, then you must also multiply 7 by 3 on the right to keep the equation a true statement.

_____

<em>If the "one-step" involves addition ...</em>

If the equation had been ...

r + 3 = 7

Then the operation you need to "undo" is the addition of 3. That is accomplished by adding -3 to both sides of the equation. Then you have ...

r + 3 - 3 = 7 - 3

r + 0 = 4

r = 4

You will recognize 0 as the additive identity element: r + 0 = r. In order to get that (0) as a sum, you need to add opposites: +3 -3 = 0. Again, you have to do the same thing (add -3) to both sides of the equation in order to keep it true.
