Answer: 
C. 
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:


Let us solve our inequality to find the monthly sales (x).
Subtract 700 from both sides of our inequality.
 
 

Divide both sides of inequality by 0.02.



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

Answer: False
Step-by-step explanation:
 
        
             
        
        
        
Since the given figure is a trapezoid, here is how we are going to find for the value of x. Firstly, the sum of the bases of the trapezoid is always equal to twice of the median. So it would look like this. 2M = A + B.
Plug in the given values above.
2M = (<span>3x+1) + (7x+1)
2(10) = 10x + 2
20 = 10x + 2
20 - 2 = 10x
18 = 10x < divide both sides by 10 and we get,
1.8 = x
Therefore, the value of x in the given trapezoid is 1.8. Hope this is the answer that you are looking for.
