Given parameters:

Cost of paint per month = $320

Cost of quality plain shirts  = $9 each

Selling price  = $24

Rent per month  = $100

Unknown:

Number of shirts Sam has to sell to break even  = ?

Solution :

 Let the number of shirt sold each month  = y

To break even the cost price per shirt must be equal to the selling price;

   i.e;

      Cost price  = selling price at break even point;

Cost price = Cost of paint + Cost of quality plain shirt + Cost of rent

                  = 320 + 9y + 100

                  = 420 + 9y

Selling price =  24y

To break even;

                      420 + 9y  = 24y

                      420  = j24y - 9y

                      420 = 15y

                          y  = [tex]\frac{420}{15}[/tex]  = 28

To break even, Sam must sell 28 shirts in a month.

Answer:

Population of bacteria in culture after 14 hours is 285541.

Step-by-step explanation:

We are given with [tex]P_{t} =P_{0}(2)^{\frac{d}{t}}[/tex]

Here initial population is 41000 , t=5 and d=14

Plug in these values into the formula

[tex]P_{14} =41000(2)^{\frac{14}{5} }[/tex]

Simplify

[tex]P_{14}= 41000(2)^{2.8}[/tex]

     =41000(6.9644)

     =285540.5847...

To the nearest whole number is 285541.

Answer:

285541.

Step-by-step explanation:

P0=41000-The initial population

t=14-Time elapsed

d=5-The doubling time

Pt=P0⋅2^t/d

Pt=41000⋅2^14/5-Plug in

Pt=285540.5848≈285541-(Use parenthesis in the calculator for the exponent)

Answer:

Expression.

Step-by-step explanation:An expression containing variables, numbers, and operation symbols is called an algebraic expression. is an example of an algebraic expression. Each expression is made up of terms. A term can be a signed number, a variable, or a constant multiplied by a variable or variables.

An expression is a number, a variable, or a combination of numbers and variables and operation symbols.

An expression is combination of variables, numbers and operators.

An expression is a number, a variable, or a combination of numbers and variables and operation symbols.

For example 2x+3y-4

In the given expression x and y are the variables.

plus and minus are the operation symbols.

4 is a number and 2 and 3 are the coefficients of a variable.

If the expression has an equal sign then it becomes the equation.

Hence, an expression is a number, a variable, or a combination of numbers and variables and operation symbols.

X=3

Step-by-step explanation:

6x=27-9

6x=18/6

x=3

Answer:

x=3

Step-by-step explanation:

Alrighty lets begin.

First, subtract 9 from 9 and from 27. Your equation will look like:

6x=18

Now, divide 6 from 6x and from 18. It would look like:

6x/6 = 18/6

Then cancel out the 6's.

And finally, simplify 18/6 and you get 3.

Your answer is x = 3

Step-by-step explanation:

Answer:

Sunayana's income is ₹25000 and expenditures are ₹15000.

Step-by-step explanation:

Let i denote the monthly income and e denote the expenditures.

We know that the ratio of the monthly income to expenditure is 5:3. So, we can write the following proportion:  

[tex]\displaystyle \frac{i}{e}=\frac{5}{3}[/tex]

Let's multiply both sides by e. This yields:

[tex]\displaystyle i=\frac{5}{3}e[/tex]

We know that when the income is increased by 5000 and the expenditures are decreased by 3000, the new ratio is 5:2. So, we can write the following proportion:

[tex]\displaystyle \frac{i+5000}{e-3000}=\frac{5}{2}[/tex]

Let's multiply both sides by [tex](e-3000)[/tex]:

[tex]\displaystyle i+5000=\frac{5}{2}(e-3000)[/tex]

Since we know that [tex]i=\frac{5}{3}e[/tex], substitute:

[tex]\displaystyle \frac{5}{3}e+5000=\frac{5}{2}(e-3000)[/tex]

So, let's solve for the expenditures. Distribute the right:

[tex]\displaystyle \frac{5}{3}e+5000=\frac{5}{2}e-7500[/tex]

Subtract [tex]\frac{5}{2}e[/tex] from both sides:

[tex]\displaystyle -\frac{5}{6}e+5000=-7500[/tex]

Subtract 5000 from both sides:

[tex]\displaystyle -\frac{5}{6}e=-12500[/tex]

Multiply both sides by -6/5. So, the expenditures are:

[tex]e=\text{Rs }15000[/tex]

We can use the original ratio to find Sunayana's income:

[tex]\displaystyle i=\frac{5}{3}e[/tex]

Substitute 15000 for e. Evaluate:

[tex]\displaystyle i=\frac{5}{3}(15000)=\text{Rs }25000[/tex]

So, Sunayana's income is ₹25000 and expenditures are ₹15000.

And we're done!

Answer: Income = 25000, Expenditures = 15000

Step-by-step explanation:

A ratio of 5:3 can also be written in fraction form as [tex]\dfrac{5}{3}[/tex] (which is in simplified format from [tex]\dfrac{5x}{3x}[/tex]).

Adding 5000 to 5x results in 5x + 5000

Subtracting 3000 from 3x results in 3x - 3000

--> [tex]\dfrac{5x+5000}{3x-3000}[/tex]

The new ratio of 5:2 can be written in simplified fraction form of [tex]\dfrac{5}{2}[/tex].

Set the fractions equal to each. Then cross multiply and solve for x.

   [tex]\dfrac{5x+5000}{3x-3000}=\dfrac{5}{2}[/tex]

5(3x - 3000) = 2(5x + 5000)             Cross multiplied

15x - 15000 = 10x + 10000                Distributed

5x - 15000 =            10000                Subtracted 0x from both sides

5x               =            25000               Added 15000 to both sides

               x = 5000                            Divided 5 from both sides

The original ratio of 5 : 3     -->  5x:3x

where 5x is the income and 3x is the expenditures results in:

income = 5x                            expenditures = 3x

             = 5(5000)                                         = 3(5000)

             = 25000                                          = 15000

x = -8.4

The inverse of division is multiplication, so:

x/1.2 = -7 (x 1.2) - multiply by 1.2

x = -8.4

Answer:

RS = 8

Step-by-step explanation:

Given that R is on QS , then

QR + RS = QS , substitute values

3x - 8 + 2x = 3x , that is

5x - 8 = 3x ( subtract 3x from both sides )

2x - 8 = 0 ( add 8 to both sides )

2x = 8 ( divide both sides by 2 )

x = 4

Thus

RS = 2x = 2 × 4 = 8
