Decimal Constructed and Ben start a business selling popsicles at a park near their house . Their first day selling popsicles they earn $ 17.83. Molly and Ben try to estimate how much money they will eam in ten days Ben they will earn about 200 in ten days because $17.83 rounds to $20 and 20x10 = 5200 . Is correct in his estimate ? Explain how you know.

Although Ben’s math has no mistakes, I would say that his estimate is incorrect. I say this because of two reasons. Number one is that Ben hasn’t had enough experience, meaning that he hasn’t sold popsicles enough days to fully estimate his total earnings. Secondly, a more exact estimate would be if he rounded up to $18 instead of $20. If he were to round up to $18, he would get an estimation of $180, $20 under his first estimation of $200.
