Mr. Larson bought a bag of chocolate. Of course, his kids want some. Mr. Larson is wise enough to get his 8 pieces first. He then divides the remaining pieces among his 9 kids and each kid ends up with 8 pieces. How many pieces were in the bag to start with?

80?

Step-by-step explanation:

if there are 9 kids and every kid ends up with 8 pieces, then you do 8x9 which is 72. ut then you add 8 bc larson got his pieces.  so the answer is 80 im pretty sure
