After sharing 100 stickers with her friends, Xia had five sheets of stickers left. If each sheet had ten stickers on it, how many stickers did Xia have at the beginning? Think carefully first, then make a decision:
Five sheet have 5 x 10 = 50 stickers. Therefore, Xia had 100 + 50 = 150 stickers at the beginning. So, the answer is 150.
