Question: Abie had 20 bags of chips. She gave 4 bags to her friend and bought another 6 bags of chips in the store. How many bags of chips does Abie have in the end? Think carefully first, then make a decision:
Abie had 20 - 4 = 16 bags of chips after giving 4 bags of chips to her friend. Abie has 16 + 6 = 22 bags of chips in the end. So the answer is 22.
