Mrs. Henry opened a bag of sugar. She poured 1,500 grams of sugar into 5 beakers and 500 grams of sugar into 4 beakers. She had 500 grams left over. What was the mass of the bag of sugar in kilograms before Mrs. Henry opened it?

2,500 grams

Step-by-step explanation:

In order to pour the sugar into the beakers and have some left over, you would need to have that much sugar. So, you would add all the amount of sugar, including the remaining.

Work:

1500+500+500 = 2,500
