Question

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 1

Answer:

The equation that best describes the situation is:

$g +400 -1800 = 1,500$

Step-by-step explanation:

The initial amount of gravel is g.

$g$

Then we know that 400 pounds are added

$g +400$

Two orders of 900 pounds are sold and the gravel is removed from the mound. This is:

$g +400 -2 * 900$

$g +400 -1800$

At the end of the day, the mound has 1,500 pounds of serious. This is:

$g +400 -1800 = 1,500$

The equation that best describes the situation is:

$g +400 -1800 = 1,500$

And

$g= 1500 +1800 - 400\\\\g=2900$
