The Oliver Company plans to market a new dish washing detergent. The selling price will be $4
per container. Variable costs are estimated to be 46% of the selling price. Fixed costs are
estimated to be $6,115. What is the break-even point? That is, how many containers of the
detergent the company must sell in order to end up with no loss and no profit in its operations?
(Round your final answer to the nearest whole number).
Answers
Answer: 2,831 containers
Step-by-step explanation:
To find the breakeven point, use the following formula:
= Fixed cost / Contribution margin
Fixed cost = $6,115
Contribution margin = Selling price - Variable cost
= 4 - (4 * 46%)
= $2.16
Breakeven point = 6,115/2.16
= 2,831 containers

Answers
Answer:
234
Step-by-step explanation:
So what we know is that
5x+9x= students
This equation is saying that for every 5 boys there are 9 girls
we can then plug in 364 for the number of students and add like terms
This means that 14x=364
this means that x=26
This means that there are 26 sets of 5 boys and 9 girls
this means that there are

[tex]\left \{ {{y=10,3-2x} \atop {y=14,8-3x}} \right.[/tex]
10,3-2x=14,8-3x
x=4,5 - one hamburger

They both agreed they should first subtract 2x and add 8 to both sides and rewrite the equation as

Then Esma said, "I can complete the square. I can add 1 to both sides to rewrite this equation as
22 + 6x + 9 = 1, factor, and solve using square roots."
Hunter said, "I'll factor the left-hand side of the equation as (x + 2)(x + 4) and solve using the zero

What is a quadratic equaton?A quadratic equation is an algebraic expression in the form of variables and constants.
A quadratic equation has two roots as its degree is two.
Given a quadratic equation x² + 8x = 2x - 8.
They both agreed that first subtract 2x and add 8 to both sides and rewrite the equation as
x² + 6x + 8 = 0.
Both of their strategies would work.
As x² + 6x + 9 = 1
(x + 3)² = 1.
x + 3 = ± 1
x = ± 1 - 3.
x = - 2 or - 4.
x² + 6x + 8 = 0.
x² + 4x + 2x + 8 = 0.
x(x + 4) + 2(x + 4) = 0.
(x + 4)(x + 2) = 0.
x = - 4 or x = - 2.

Howard buys a new comforter set for 15% off the original price of 54$.What is the sale price?
Answers
Answer:
$45.90
Step-by-step explanation:
What 15% off means is 85% of the original price ($54). 85% is the same as 17/20. Multiply 17/20 by 54 (or multiply 3/20 by 54 and subtract that from 54) to get the sale price.
(17 * 54)/20 (Multiply 17 by 54)
918/20 (Reduce if needed)
459/10 (Divide 459 by 10)
45.9
The sale price of the comforter is $45.90.
What percent of 25 is 50
Answers
Answer:
50 is 200% of 25
Step-by-step explanation:
50 is 200 percent of 25.
To find the percentage of one number in relation to another, we can use the following formula:
(Percentage / 100) * Base = Amount
In this case, we want to find what percentage of 25 is 50.
Let's use x to represent the percentage:
(x / 100) * 25 = 50
To solve for x, we can divide both sides of the equation by 25:
(x / 100) = 50 / 25
Simplifying:
(x / 100) = 2
Next, we can cross-multiply:
x = 100 * 2
Simplifying:
x = 200
Therefore, 50 is 200% of 25.

the annual interest rate was 4%, how long would it take
to double his initial investment?
A)16 year
B)17
C)18
None of the above
Answers
Answer:
None of the above
Step-by-step explanation:
The correct answer to the given question is None of the above
Assuming simple rate
The calculation is shown below
$50,000 * 4% = $2,000
this makes an interest of $2,000 per year.
$2,000 / $50,000 = 25 years
It will take 25 years to double Mr. Escobars initial investment so the answer is none of the above.

Fifteen hungry kittens found a bucket of sausages. Each time they cut a sausage or a part of a sausage, they cut it into exactly two new pieces. They made 20 cuts in all and each kitten got 2 (maybe unequal) pieces of sausage. How many sausages were in the bucket?
Answers
Answer:
There is a total of 10 sausages. I am 100% sure.
Step-by-step explanation:
A bucket of sausages fed 15 hungry kittens. Each sausage or half of a sausage is sliced into two pieces. They chopped 20 sausages and gave each kitten two (perhaps unequal) portions. Therefore, there were 34,952 sausages in the bucket.
At the start, there is one sausage bucket, and the 15 kittens want to share it.
The first cut divides the sausage into two pieces.
After the second cut, there are four pieces of sausage.
After the third cut, there are eight pieces.
After the fourth cut, there are 16 pieces.
As we can observe, the number of pieces of sausage doubles with each cut. After 20 cuts, there will be 2²⁰ (2 raised to the power of 20) pieces of sausage.
Now, since each kitten received two pieces of sausage, the total number of sausages in the bucket can be calculated by dividing the total number of pieces by 2 × 15 (since there are 15 kittens).
Total sausages = (2²⁰) / (2 × 15)
Let's simplify this:
Total sausages = 2¹⁹ / 15
Now, let's calculate the value:
Total sausages = 524,288 / 15
Total sausages = 34,952.53
Since you can't have a fraction of a sausage, we need to round down to the nearest whole number.
Therefore, there were 34,952 sausages in the bucket.
