Sure, let me help you on this one!
If Larissa earns $500 per week, she will need $250 more in order for her to reach the desired salary of $750 per week.
I am afraid you are lacking some information in the question, since you didn't specify the percentage of the commission Larissa is permitted to take, but for the sake of helping you understand the structure of this question, I will make it 100% - all of the sales money go to Larissa.
If that's true, Larissa will only need to sell enough stuff for $250.
If the commission was 50%, Larissa would have to sell enough stuff for $500 since 50% of her sales are taken.

I hope this helped you, and feel free to re-ask me this question when you have all of the information required.
Step-by-step explanation:
The way that I would do it, would be to use the point distance formula to find the length of each side.
Distance formula: 
After you use this formula to find the length of all sides of the polygon, you would need to use the appropriate area formula to find the area of the polygon.
Area of Triangle: A= 1/2 base times height
Area of Rectangle: A= length times width
Area of Square: A= s^2 where s is the length of the side
Area of Parallelogram: A= base times height
Area of Trapezoid: A= 1/2 times height (base 1 + base 2) where base 1 and base 2 are the parallel sides
Area of Kite or Rhombus: A= 1/2 (diagonal 1 times diagonal 2)
Area of Regular Polygons: A= 1/2 (apothem times perimeter)
False. The absolute value of any integer is ALWAYS positive. So, the absolute value of a positive integer would be positive. Hope this helps :)
