A salesperson earns a salary of $700 per month plus 2% of the sales. Which inequality correctly represents the total sales if th

My name is Ann [436]

Answer:

C. $x\geq 55000$

Step-by-step explanation:

Let x be the total monthly sales.

We have been given that a salesperson earns a salary of $700 per month plus 2% of the sales. The salesperson want to have a monthly income of at least $1800.

This means that 700 plus 2% of total monthly sales should be greater than or equal to 1800. We can represent this information in an equation as:

$700+(\frac{2}{100})x\geq 1800$

$700+0.02x\geq 1800$

Let us solve our inequality to find the monthly sales (x).

Subtract 700 from both sides of our inequality.

$700-700+0.02x\geq 1800-700$

$0.02x\geq 1100$

Divide both sides of inequality by 0.02.

$\frac{0.02x}{0.02}\geq \frac{1100}{0.02}$

$x\geq \frac{1100}{0.02}$

$x\geq 55000$

Therefore, the total monthly sales must be greater than or equal to 55,000 and option C is the correct choice.

Find the area under the standard normal curve to the left of

JulijaS [17]

A. z = 0.74
The z-score of 0.74 translates to a percentile of 0.77035. Hence, the area under the standard normal curve to the left of z-score 0.74 is ~0.77.

b. z = -2.16
This z-score translates to a percentile of 0.015386 which is also the numerical value of the area under the curve to the left of the z-score

c. z = 1.02
The percentile equivalent of the z-score above is 0.846. The area is also 0.846.

d. z = -0.15
The percentile equivalent and the area is equal to 0.44.
