Answer:

$2600

Step-by-step explanation:

If his monthly salary is $2000 and 2% commission.

He made $30,000 in sales for the month so lets make an equation.

s = total salary

s = $2,000 + .02($30,000)

s = $2,000 + $600

s = $2600

Randy's salary for the month is $2600.

ZanzabumX [31]

Answer:

$r=-3$

Step-by-step explanation:

The line that passes through the two points (6, -23) and (11, r) has a slope of 4.

We want to determine the missing value of r.

We can use the slope formula:

$\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Let (6, -23) be (x₁, y₁) and let (11, r) be (x₂, y₂). The final answer should be 4. Therefore:

$\displaystyle \frac{r-(-23)}{11-6}=4$

Simplify and evaluate:

$\displaystyle \frac{r+23}{5}=4$

Multiply both sides by 5:

$r+23=20$

Therefore:

$r=-3$

<h3>Answer</h3>

<h3>Explanation</h3>

$\frac{14}{10} = \frac{7}{5}$

$\frac{y + 9}{15} = \frac{y + 3}{5}$

$\frac{7}{5} = \frac{y + 3}{5} = y = \frac{7}{5} - \frac{3}{5}$

The result is very simple now: 4/5
