Gnom [1K]

Answer:

He have at the beginning inventory of <u>4,000</u>.

Step-by-step explanation:

Given:

Last month robert sold three quarters of his inventory and then bought 3,000 in new inventory.

If now he has 6,000 in inventory.

Now. to find inventory he have at the beginning of last month.

Let the inventory at the beginning of last month be $x.$

The inventory he sold last month:

$\frac{3}{4}\ of\ x$

$=\frac{3}{4} \times x$

$=\frac{3x}{4}$

Then, he bought inventory 3,000 in new inventory.

Now, he has 6,000 in inventory.

So, we set an equation to solve it:

$\frac{3x}{4} +3000=6000$

<em>Subtracting both sides by 3000 we get:</em>

$\frac{3x}{4} =3000$

<em>Multiplying both sides by 4 we get:</em>

$3x=12000$

<em>Dividing both sides by 3 we get:</em>

$x=4000.$

Therefore, he have at the beginning inventory of 4,000.

The simplification of the expression (h² + 9·h - 1) × (-4·h + 3), involves the

multiplication of the terms. The error is therefore;

3. Calculating errors when distributing -1

<h3>How can the error in the calculation be found?</h3>

The expansion of (h² + 9·h - 1) × (-4·h + 3), is given as follows;

(h² + 9·h - 1) × (-4·h + 3) = -4·h³ + 3·h² - 36·h² + 27·h + 4·h - 3

Which gives;

-4·h³ - 33·h² + 31·h - 3

The calculation is therefore;

$\begin{array}{|c|c|c|c|}&h^2&+9 \cdot h & -1\\-4 \cdot h&-4\cdot h^3&-36\cdot h^2 &4 \cdot h\\+3& 3 \cdot h^2&27 \cdot h&3\end{array}\right]$

The error is therefore, in the distribution of the -1

The correct option is;

3. Calculating errors when distributing -1
