Greg is buying a small bag of blueberries. After weighing the bag on the scale, he added 0.15 pounds of blueberries. Now the bag weighs 0.52 pounds.

Which equation can you use to find the weight of the bag before Greg added more blueberries?

b - 0.52 = 0.15
b - 0.52 = 0.15

b + 0.52 = 0.15
b + 0.52 = 0.15

b - 0.15 = 0.52
b - 0.15 = 0.52

b + 0.15 = 0.52

b - 0.15 = 0.52
