be produced and sold in order to break even. That is, find the value of x for which C = R.

C = 13x +250 and R = 15.5x.

How many units must be produced and sold in order to break even?

4

The **number **of units that must be **produced **and sold in order to **break even **will be 100.

At the **break**-**even **point, the cost of the revenue is **equal **to the cost of the **manufacturing**.

The **break**-**even **point is the point at which a business's **costs **and revenues are **equal**. R stands for the revenue, in dollars, from the **sale **of x units, and C **stands **for the cost, in dollars, of x units of a **product**.

C = 13x + 250 and R = 15.5x

By the definition of the **break**-**even **point, then the equation is given as,

13x + 250 = 15.5x

15.5x - 13x = 250

2.5x = 250

x = 250 / 2.5

x = 100

The **number **of units that must be **produced **and sold in order to **break even **will be 100.

The correct statement regarding Isaiah is that A. His **gross pay** is $3,000 and net pay is $2,500

Before **taxes**, benefits, and other payroll deductions are taken out of an employee's paycheck, that amount is known as their **gross pay**. Net pay, often known as take-home pay, is the amount that is left after all withholdings have been taken into account. Determining the number of pay periods you have throughout the year is the first step in calculating the **gross** compensation for a salaried employee.

The time range for which you pay your employee is known as a pay period. You must first determine your **employee's** gross compensation before you can determine their net pay. This is where you should start. The next thing you need to know is what **payroll** deductions your employee receives.

Since the take-home pay is $2,500, this is the **net pay.**

solve the system {x-y+z=0, 3x-2y+6z=9, -x+y-2z=-2}

The **system** of **equations** has a solution of x = -17, y = -15 and z = 2

**Linear equations **are equations that have constant average rates of change.

Note that the constant average **rates of change **can also be regarded as the slope or the gradient

A system of **linear equations** is a collection of at least two linear equations.

In this case, the **system** of **equations** is given as

x - y + z = 0

3x - 2y + 6z =9

-x + y -2z = -2

Add the first and the third **equations**

So, we have

x - x - y + y + z - 2z = 0 - 2

Evaluate

-z = -2

This gives

z = 2

Make z = 2 in the other **equations**

So, we have

x - y + 2 = 0

3x - 2y + 12 =9

-x + y - 4 = -2

This gives

x - y = -2

3x - 2y = -21

-x + y = 2

Make y the subject in -x + y = 2

y = x + 2

Substitute y = x + 2 in 3x - 2y = -21

3x - 2(x + 2) = -21

Expand

3x - 2x - 4 = -21

So, we have

x = -17

Recall that y = x + 2

So, we have

y = -17 + 2

Evaluate

y = -15

Hence, the solution for the system of **linear equations **x - y + z = 0, 3x - 2y + 6z =9 and -x + y -2z = -2 are x = -17, y = -15 and z = 2

Let be:

Then, we can write the following system of linear equations

[tex]\begin{cases}x+y=125\Rightarrow\text{ Equation 1} \\ x=45+y\Rightarrow\text{ Equation 2}\end{cases}[/tex]• Part B

To solve this question, we will solve the system of linear equations that we wrote above.

To do this, we can first substitute the value of x from Equation 2 into Equation 1, and then we solve for y:

[tex]\begin{gathered} x+y=125\Rightarrow\text{ Equation 1} \\ (45+y)+y=125 \\ 45+y+y=125 \\ \text{ Add similar terms} \\ 45+2y=125 \\ \text{ Subtract 45 from both sides of the equation} \\ 45+2y-45=125-45 \\ 2y=80 \\ \text{ Divide by 2 from both sides of the equation} \\ \frac{2y}{2}=\frac{80}{2} \\ y=40 \end{gathered}[/tex]Therefore, Angela spends 40 minutes playing golf every day.

• Part C

To solve this question, we can replace the value of y into Equation 1 and then solve for x

[tex]\begin{gathered} x+y=125\Rightarrow\text{ Equation 1} \\ x+40=125 \\ \text{ Subtract 40 from both sides of the equation} \\ x+40-40=125-40 \\ x=85 \end{gathered}[/tex]Therefore, Angela cannot possibly spend 80 minutes playing soccer every day because she actually spends 85 minutes.
