A bookstore costs $96 a day to keep open, and it spends $12 for each book that it sells. If each book sells for $18, what is the break-even point
for this bookstore?
Answers
Answer: The break even point is when they have sold 16 books and have made $288
Step-by-step explanation: The costs are modeled in the equation y = 12x + 96. x is the number of books sold.
The earnings are modeled by he equation y = 18x.
Substitute 18x for y and solve for x.
18x = 12x + 96 Subtract 12x from both sides.
6x = 96 Divide both sides by 6
x = 16
Substitute into the original equations to solve for y
y = 12(16) + 96
y = 192 + 96
Y = 288
y = 18(16)
y = 288

The system is consistent; it has one solution ⇒ D
Step-by-step explanation:
A consistent system of equations has at least one solution
The consistent independent system has exactly 1 solutionThe consistent dependent system has infinitely many solutionsAn inconsistent system has no solution
In the system of equations ax + by = c and dx + ey = f, if
a = d, b = e, and c = f, then the system is consistent dependent and has infinitely many solutionsa = d, b = e, and c ≠ f, then the system is inconsistent and has no solutiona ≠ d, and/or b ≠ e, and/or c ≠ f, then the system is consistent independent and has exactly one solutionIn the given system of equations
∵ -2y + 2x = 3 ⇒ (1)
∵ -5y + 5x = 12 ⇒ (2)
→ By comparing equations (1) and (2)
∵ -2 ≠ -5
∵ 2 ≠ 5
∵ 3 ≠ 12
→ By using the 3rd rule above
∴ The system is consistent independent and has exactly one solution
∴ The system is consistent; it has one solution
A TV originally priced at $500 is discounted 5%. How much is the discount?
Answers
Answer:
The discount price for the TV is $475
Step-by-step explanation:
You multiply the original price by 0.95 (95%)
Answer:
$400
Step-by-step explanation:
Take the original price. Divide the original price by 5. Alternatively, divide the original price by 100 and multiply it by 20. Subtract this new number from the original one.
500/100=5
5*20=100
500-100=400

Use the Substitution method to solve this system of equations:

Substitute -y-1 for x in the second equation. (We can make this move because the first equation tells us that whatever x is, it is equal to -y-1.)

x-y=-11

Simplify by combining like terms.

Answer:
5/14
Step-by-step explanation:
To work this out, we simply need to divide 1 3/4 miles by 4 9/10 miles.
1 3/4 ÷ 4 9/10
Start by converting both terms to improper fractions:
(4/4 + 3/4) ÷ (40/10 + 9/10)
= 7/4 ÷ 49/10
To divide, we simply multiply by the reciprocal of the second fraction:
7/4 * 10/49
= 70 / 196
Now we can take out common factors of the 70 / 196
70 / 196
= (5 * 2 * 7) / (14 * 2 * 7)
= 5 / 14

A list contains 7 consecutive even numbers in ascending order.The largest number is 30 and the smallest is 12 less than this.The mode is 20 and median is 22.If the sum of the two remaining numbers is 50,find all the number
Answers
Answer:
18, 20, 20, 22, 24, 26, 30
Step-by-step explanation:
We know that the largest number of the list is 30 and the smallest number is 12 less than that, which is 30 - 12 = 18.
This is our list so far: 18, __ , __ , __ , __ , __ , 30
The median of a set is the middle number of the set. In this case, since there are 7 terms in the set, the median, which the problem states is 22, must be the 4th number, since the 4th number is in the middle.
This is our list now: 18, __ , __ , 22, __ , __ , 30
Now, let's deal with the mode. The mode of a set is the term that shows up the most. Since the set is in ascending order and 20 < 22, we know that the two numbers in between 18 and 22 must be 20 and 20. This means that no term can show up more than once, with the exception of 20 because it is the mode.
This is our list now: 18, 20, 20, 22, __ , __ , 30
Finally, we'll deal with the last two numbers. We know that they must be even and that they both must be in between 22 and 30 (since the set is in ascending order). We also know that the two numbers must be different (see last paragraph) and that they sum to 50. The only two numbers that satisfy all of these conditions are 24 and 26, so they must be our last two numbers.
Therefore, the answer is 18, 20, 20, 22, 24, 26, 30. Hope this helps!

Calculate the frequency of light that has a wavelength of
4.25 x 10^-9m and a velocity of 300 m/s.
Answers
Answer:
The velocity of light, v, is the product of its wavelength, λ , and its frequency, f. This means that the wavelength is the velocity, v, divided by the frequency, f.
Wavelength of light = velocity of light / frequency of light
λ = v/f
λ = Wavelength of light, meters
v = Velocity of light (c = 3.0 x 108 m, for speed of light if not otherwise defined)
f = frequency of light, Hz

The difference between the roots of the quadratic equation x2 -14x +q =0 is 6. Find q
Answers
9514 1404 393
Answer:
q = 40
Step-by-step explanation:
When the quadratic has roots p and r, it can be factored as ...
(x -p)(x -r) = x² -(p+r)x +pr
So, the sum of the roots is 14, and their difference is 6. This lets us find the roots from ...
p + r = 14
p - r = 6
2p = 20 . . . add the two equations
p = 10
r = 14 -p = 4
The value of interest is then ...
q = pr = (10)(4)
q = 40
__
The graph shows the roots to be 4 and 10, as we found.
