3F furniture dealer has always sold its merchandise through 4 company-operated
stores. Last year sales were birr 1million and net profit was 8% of sales. Fixed
costs were birr 170,000. As a result of shifting population and increased
competition, the four locations have become less desirable. 3F is considering
eliminating its retail stores in favor of door-to-door selling. It is estimated that
sales would increase by 25% and net profit by birr 30,000. Fixed costs would
increase by birr 30,000 because operations would be moved to a low-rent
warehouse. Required
a) What was the break-even point under the old situation?
b) What will be the break-even point under the proposed situation?
c) What birr sales volume must be obtained under the proposed plan to make as
much profit as last year?
The break-even point under the old situation is 680000, the break-even point under the proposed situation is 806451 and the birr sales volume must be obtained under the proposed plan to make as much profit as last year is 1129032.
Define breakeven point.In economics, business, and particularly cost accounting, the break-even point is the point at which total cost and total income are equal, or "even." Although opportunity costs have been paid and capital has obtained the risk-adjusted, projected return, there is no net loss or gain, and one has "broken even."
In the given question, last year sales= birr 100000
net profit= 8% of sales
Fixed costs= birr 170000
Estimated sales increase= 25%
Estimated net profit= birr 30000
Increase in fixed cost due to moving to low-rent warehouse= birr 30000
(a) The break-even point under the old situation (X):
= 100,000 * a - 170,000
=1,000,000 * 8%
a= 25% (net profit)
X*a= 1170,000
X=680,000
That is, the break-even point under the old situation is 680000.
(b) The break-even point under the proposed situation is:
= 1,250,000 x b - 170,000- 30,000
= 80,000 + 30,000
b= 24.8%
X*b=200,00
X=806451
The break-even point under the proposed situation is 806451 and
(c) The birr sales volume must be obtained under the proposed plan to make as much profit as last year is:
X*b -200,000= 80,000
X*b = 280,00
X= 1,129,032
The birr sales volume must be obtained under the proposed plan to make as much profit as last year is 1129032.

For a certain company, the cost function for producing x items is C(x)=50x+100 and the revenue function for selling x items is R(x)=−0.5(x−90)2+4,050 . The maximum capacity of the company is 150 items.
Assuming that the company sells all that it produces, what is the profit function?
P(x)=
What is the domain of P(x) ?
The company can choose to produce either 40 or 50 items. What is their profit for each case, and which level of production should they choose?
Profit when producing 40 items =
Profit when producing 50 items =
Can you explain, from our model, why the company makes less profit when producing 10 more units?
The profit function is P(x) = −0.5x² + 40x - 100
The domain is 3 < x < 75Profit when producing 40 items = 700Profit when producing 50 items = 650The company makes less profit when they produce moreHow to determine the profit function?From the question, we have the following equations that can be used in our computation:
Cost function, C(x) = 50x + 100
Revenue function, R(x) = −0.5(x − 90)² + 4050
The profit function is the difference between the revenue and the cost
So, we have
P(x) = R(x) -CP(x)
Substitute the known values in the above equation, so, we have the following representation
P(x) = −0.5(x − 90)² + 4050 - 50x - 100
Evaluate the like terms
P(x) = −0.5(x − 90)² - 50x + 3950
Expand
P(x) = −0.5(x² − 180x + 8100) - 50x + 3950
Expand
P(x) = −0.5x² + 90x - 4050 - 50x + 3950
Evaluate the like terms
P(x) = −0.5x² + 40x - 100
The domain of the functionIn (a), we have
P(x) = −0.5x² + 40x - 100
Using a graphing calculator, the reasonable domain is
3 < x < 75
So, the domain is 3 < x < 75
The profit at each productHere, we have
x = 40 or 50
So, we have
P(40) = -0.5(40)² + 40(40) - 100 = 700
P(50) = -0.5(50)² + 40(50) - 100 = 650
Why the profit makes less profitIn (d), we have
P(40) = 700
P(50) = 650
This means that the profit reduces as they produce more

The other roots of the cubic equation p(x) = 24·x³ - 46·x³ + 29·x - 6 are;
x = 1/2
x = 3/4
What is a cubic equation in mathematics?A cubic equation is an equation that has 3 as the highest index.
The specified polynomial in the question is presented as follows;
P(x) = 24·x³ - 46·x² + 29·x - 6
The solution of the equation is; x = (2/3)
Therefore, (x - 2/3) is a factor of the equation and we get;
(24·x³ - 46·x² + 29·x - 6) ÷ (x - 2/3) has a remainder of 0
Dividing the above expression using long division, we get;
24·x² - 30·x + 9

The other real roots of the specified equation can be found as follows;
The equation for the roots is; P(x) = 24·x³ - 46·x² + 29·x - 6 = 0
From the above long division, therefore;
24·x³ - 46·x² + 29·x - 6 = (24·x² - 30·x + 9) × (x - 2/3) = 0
Which indicates; (24·x² - 30·x + 9) = 0 or (x - 2/3) = 0
The other solution are;
24·x³ - 30·x + 9 = 0
3·(·8·x² - 10·x + 3) = 0
8·x² - 10·x + 3 = 0
Solutions for the above equation in the form; a·x² + b·x + c = 0 can be obtained using the quadratic formula as follows;
The quadratic formula; x = [tex]\dfrac{-b\pm\sqrt{b^2 - 4\cdot a\cdot c} }{2\cdot a}[/tex]
By comparing the equation, 8·x² - 10·x + 3 = 0 to the equation, a·x² + b·x + c = 0, we get;
a = 8, b = -10, and c = 3
Therefore;
x = (10 ± √((-10)² - 4 × 8 × 3))/(2 × 8)
((-10)² - 4 × 8 ×3) = 2
Therefore;
x = (10 ± √((-10)² - 4 × 8 × 3))/(2 × 8) = (10 ± 2)/(16)
x = 3/4, and x = 1/2
Therefore, the other other roots in increasing sequence are;

Determine the student’s average speed. ________
m/s
The total distance covered is 15000 m. The total time taken is 5220 seconds and the speed is 2.87 m/s.
What is the speed?We know that speed has to do with the ratio of the distance that has been covered to the time taken. The speed is a scalar quantity and as such we do not consider the direction hence we would not consider that going back in the opposite direction. The total distance can be obtained algebraically.
The total distance that the student travelled can be obtained from;
5000 m + 5000 m + 5000 m

the scores on Exam 1 is 0.51. The standard deviation for
Exam 1 scores is 11.6, and the standard deviation for Exam
2 scores is 7.0. Use only this information to find the
correlation between Exam 1 scores and Exam 2 scores.
The correlation coefficient between Exam 1 scores and Exam 2 scores is given as follows:
0.8452.
How to obtain the correlation coefficient?The equation for this problem is given as follows:
b = r x Sy/Sx.
The variables of the equation are given as follows:
b is the slope.r is the correlation coefficient.Sy is the standard deviation of the output variable.Sx is the standard deviation of the input variable.The input and the output variables in this problem are given as follows:
Input variable: Exam 1 score.Output variable: Exam 2 score.Hence the values of the parameters are given as follows:
b = 0.51, Sx = 11.6, Sy = 7.
Hence the numeric value of the correlation coefficient is obtained as follows:
b = r x Sy/Sx.
r x 7/11.6 = 0.51
0.6034r = 0.51
r = 0.51/0.6034
r = 0.8452.
