Question

There is a mound of g pounds of gravel in a quarry. Throughout the day, 200 pounds of gravel is added to the mound. Two orders of 700 pounds are sold and the gravel is removed from the mound. At the end of the day, the mound has 1,100 pounds of gravel. solve for g​

Answer 1

Starting amount = g

Throughout the day 200 pounds is added and 1400 pounds is removed ( 700 x 2 = 1400)

Final weight is 1,100 pounds

g + 200 - 1400 = 1100

Simplify:

g - 1200 = 1100

Add 1200 to both sides:

g = 2300 pounds
