Question s Incomplete; Complete question is given below;
There is a mound of g pounds of gravel in a quarry. Throughout the day, 400 pounds of gravel are added to the mound. Two orders of 900 pounds are sold and the gravel is removed from the mound. At the end of the day, the mound has 1,500 pounds of gravel. Write the equation that best describes the situation.
Answer:
The equation that best describes the situation is
.
Step-by-step explanation:
Given:
Amount of gravel present initially = '
'.
Now Given:
Throughout the day, 400 pounds of gravel are added to the mound.
So we can say that;
Amount of gravel after addition = 
Also given:
Two orders of 900 pounds are sold and the gravel is removed from the mound.
Now Two orders of 900 pounds = 
So we can say that;
Amount of gravel after removing = 
Now Given:
Amount left in mount at the end of the day = 1300 pounds.
So we can say that;

Hence the equation that best describes the situation is
.
It's B. Since the slope is -8/1 x. Slope is rise/run. The other answers doesn't make sense since the x is put in a different place.
The surface area of the box will be 112 in²
Explanation
According to the given diagram, the shape of the box is Right Rectangular prism.
The formula for the surface area is :
, where
length,
width and
height of the rectangular prism
Given in the diagram that, 
So, plugging the values into the formula...

So, the surface area of the box is 112 in²
