A store purchased a digital camera and marked it up 100% from the original cost of $863.57.
A week later, the store placed the digital camera on sale for 40% off. What was the discount
Answer:
$690.86
Step-by-step explanation:
100% from the original cost is: 2 x 863.57 = $1,727.14
40/100 = X/1727.14 (40 percent is what of 1,727.40) (%/100 = is/of)
(40 * 1,727.14) / 100 = $ 690.86

Ajar contains 3 red and 5 green balls identical in all aspects except color. If two balls are drawn at random, then the probability that the two balls drawn are not green is
Answer:
3/28.
Step-by-step explanation:
Total of 8 balls in the jar.
Prob (first one not green (= that its red) = 3/8
Prob ( Second one is also red) = 2/7.
So probability that both are not green = 3/8 * 2/7
= 6/56
= 3/28.

What equation is graphed?
Find the slope and y-intercept for this table.
Answer:
See below:
Step-by-step explanation:
To find the slope, we use the following formula:
[tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]
For this case, we can use (6,60) as the first set of points.
We can use (4,70) as the second set of points.
Now, we can use the formula, 70-60 is for the top of the fraction (10)
We can do 4-6 to find the bottom, which is (-2)
Now, if we add the fraction back we get -> 10/-2 which is -5 for slope!
To find out the y intercept, it in simple words is "What is y when x is 0?".
We can do that by using the slope intercept formula: [tex]y=mx+b[/tex].
Once we insert our slope which is -2 we get: [tex]y=-2x+b[/tex]
We can now substitute a point, lets use (6,60) so we can find out b.
We now get the equation: [tex]60=-5(6)+b[/tex].
If we solve for that we get 90!
Once we input that, we get, [tex]y=-5x+90[/tex]
Now we put in x as 0 and we get our y intercept as 90!

7.C.J. says the quotient of -3/4 divided by 1/4 is - 1/3
a What is the correct quotient?
bWhat mistake did CJ likely make?
a. He multiplied the reciprocals of both fractions.
b. He added -3/4 and 1/4
c. He multiplied-3/4 by 1/4
d. He multiplied using the reciprocal of -3/4.
The correct quotient is -3
The mistake CJ likely made is multiplying using the reciprocal of -3/4. The correct option is d. He multiplied using the reciprocal of -3/4
From the question,
We are to determine the correct quotient.
The given division operation to be carried out is -3/4 divided by 1/4
The correct quotient can be determined as shown below
[tex]-\frac{3}{4} \div \frac{1}{4}[/tex]
Multiply [tex]-\frac{3}{4}[/tex] by the reciprocal of [tex]\frac{1}{4}[/tex]
The reciprocal of [tex]\frac{1}{4}[/tex] is [tex]\frac{4}{1}[/tex]
Then, we get
[tex]-\frac{3}{4} \times \frac{4}{1}[/tex]
This gives
[tex]-\frac{12}{4}[/tex]
= -3
The correct quotient is -3
The mistake CJ likely made is multiplying using the reciprocal of -3/4.
Hence, the correct quotient is -3
The mistake CJ likely made is He multiplied using the reciprocal of -3/4. The correct option is d. He multiplied using the reciprocal of -3/4

Which could be the transformation or sequence of transformations?
Select all that apply.
Answer: A
B
D
Step-by-step explanation:just trust me bro its the answer
The transformation is the rotation of 180° about the origin. Therefore, option B is the correct answer.
Given that, quadrilateral EFGH is the image of ABCD after a transformation or sequence of transformations.
We need to find which could be the transformation or sequence of transformations.
What are the transformations?A function, f, that maps to itself are called the transformation, i.e., f: X → X. The pre-image X becomes the image X after the transformation. This transformation can be any or the combination of operations like translation, rotation, reflection, and dilation. The translation is moving a function in a specific direction, rotation is spinning the function about a point, reflection is the mirror image of the function, and dilation is the scaling of a function.
Rotation 180°: The rule for a rotation by 180° about the origin is (x,y)→(−x,−y).
From quadrilateral EFGH to the image of ABCD the transformation is the rotation of 180°.
Therefore, option B is the correct answer.

Now when the spending multiplier is same as the one calculated in Q 4c and if there is a decrease in government purchases by $50,000. Calculate the change in AD. (Show your work)
Will AD increase or decrease?
Answer:
a. The real GDP increases by $200,000.
a. The real GDP increases by $150,000.
Step-by-step explanation:
a. What is the eventual effect on real GDP if the government increases its purchases of goods and services by $50,000?
Eventual effect on real GDP = Amount of increase in government spending * (1 /(1 - MPC)) = $50,000 * (1 / (1 – 0.75)) = $200,000
Therefore, the real GDP increases by $200,000.
a. What is the eventual effect on real GDP if the government, instead of changing its spending, increases transfers by $50,000?
Eventual effect on real GDP = (Amount of increase in government transfers * (1 /(1 - MPC))) - Amount of increase in government transfers = ($50,000 * (1 / (1 – 0.75))) - $50,000 = $150,000
Therefore, the real GDP increases by $150,000.
