The Bridal Shop bought a dress from a supplier for $105 wholesale and applied a 65% markup to the price.
If a 7.5% sales tax were added after a 20% discount was used, what would be the total cost to purchase the dress?
A
$146.20

B
$149.00

C
$158.48

D
$160.17

Answers

Answer:

B $149.00

Step-by-step explanation:

105 * 1.65 =   173.25      (100%+ 65%)    Price with the markup            

173.25 *0.80  138.60  (Price after 20% discount .The price will be the 80%)    

138.60 * 1.075 =   148.995  (price with 7.5  sales tax.)

at the grocery store, 8 oranges cost $4. What is the cost for 9 oranges

Answers

Answer:

$4.50

Step-by-step explanation:

so if each orange is $0.5 you can multiply it by 9 which is the amount of oranges there are

9 * 0.5 = $4.50

what is the slope of the line passes through the points (-3, -3) and (-5, -2) in simplest form help me

Answers

Answer:

Slope, [tex]m=\dfrac{-1}{2}[/tex]

Step-by-step explanation:

We need to find the slope of the line passes through the points (-3, -3) and (-5, -2).

The formula for the slope of a line is given by :

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

Put x₁ = -3, y₁ = -3, x₂ =-5 and y₂ = -2

So,

[tex]m=\dfrac{-2-(-3)}{-5-(-3)}\\\\m=\dfrac{-1}{2}[/tex]

So, the slope of the line is [tex]\dfrac{-1}{2}[/tex].

- 10x -12 = -12x + 4
Solve for x pls

Answers

Answer:

x=8

Step-by-step explanation:

- 10x -12 = -12x + 4

-10x+12x=4+12

2x=16

x=8

Answer:

x = 8

Explanation:- 10x -12 = -12x + 4Add 12x to both sides

−10x − 12 + 12x = −12x + 4 + 12x

2x − 12 = 4

Add 12 to both sides

2x − 12 + 12 = 4 + 12

2x = 16

Divide both sides by 2

2x / 2 = 16 / 2

x = 8

Elizabeth changed her time for the mile walk from 30 minutes to 24 minutes. What was the percent of change?​

Answers

-20%

Basically, we are trying to find the change from 30 to 24 in terms of percent. We do this in three steps:

1) Find the difference between 30 and 24 as a number.

2) Divide the result from Step 1 by the starting number 30.

3) Multiply the result from Step 2 by 100 to get it in terms of percent.

The three steps above can be made into a formula. Thus, to find the percent change from 30 to 24, we use this formula:

((Y-X)/X)*100 = Percent Change

X is the starting number 30, and Y is the ending number 24 that it changed to. When we enter these numbers into the formula, we get:

((24-30)/30)*100 = -20.00%

Thus, the answer to the question "What is the Percent Change from 30 to 24?" is:

-20.00%

Kara is the manager of a video game store. She is in charge of buying the video games for the store to sell. She buys video games from a wholesaler that sells them for $10

each. The wholesaler also charges a fee of $160 for each bulk purchase. Kara then sells the video games for $14 each.

Write an equation to represent the cost to buy videos from the wholesaler. Let x represent the number of videos bought. Let y represent the total cost in dollars.

Answers

Answer: y = 10x + 160

Step-by-step explanation:

The cost follows the linear equation format of:

y = mx + c

Where:

y = dependent variable or the total cost

m is the cost per each additional unit of x

x is the number of video games

c is the constant cost or rather the fee per bulk purchase

Formula is therefore:

y = 10x + 160

Using the formula. Assuming Kara buys 100 video games, the cost would be:

y = 10 * 100 + 160

y = $1,160

Answer:

Step-by-step explanation:

Answer:

Multiply both the numerator and the denominator by the same whole number.

For example;

If you multiply 1/2 by 2/2, this will equal 2/4. You can simplify 2/4 to 1/2.

So to find 1/2 to be equivalent to another fraction, multiply both the numerator and the denominator by the same number to find a fraction that equals 1/2.
