For the pyramids, use the formula:(length)(length)(base)(1/3)

For the cones, use the formula: (length of circle/2)²(3.14)(height)(1/3)

So just plug in the numbers into these formulas.

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.
