Alan has an annual base salary of $18,000. In addition to his salary, he earns 9% of his total sales (S). If he wants to earn at
aivan3 [116]

The right answer is Option D: S>$300,000.

Step-by-step explanation:

Given,

Base salary of Alan = $18000

Commission = 9% = \frac{9}{100} = 0.09

Amount Alan wants to earn = $45000 or more

Let,

s be the worth he needs to sell.

Therefore,

Base salary + Commission*Total sales>Amount Alan wants to earn

18000+0.09s>45000

0.09s>45000-18000\\0.09s>27000

Dividing both sides by 0.09

\frac{0.09s}{0.09}>\frac{27000}{0.09}\\s>300000

Alan must sold items that worth at least $300,000.

The right answer is Option D: S>$300,000.

Find the inequality represented by the graph?
vitfil [10]

Answer:

y > -2/3x + 3

Step-by-step explanation:

Well lets first start with the beginning and look at its features.

<u>                                                           Features                                                          </u>

- Dashed line

- Shaded up

- negative slope

- y intercept at 3

____________________________________________________________

So if the line is dashed with the shade going up that means the inequality starts like this,

y >

We can tell that the y intercept is at 3 because that the point the line touches the y axis.

So we got y > 3,

To find slope we use the following formula,

\frac{y^2-y^1}{x^2-x^1},

So we can use points (0,3) and (3,1).

1 is y2 and 3 is y1 so 1 - 3 = -2

3 - 0 = 3

Slope: -2/3x

<em>Thus,</em>

<em>the inequality is y > -2/3x + 3.</em>

<em />

<em>Hope this helps :)</em>
