Amy will win a prize if she sells 300 boxes of cookies. She sells 51 boxes in January and
104 boxes in February. Should Amy round to the nearest hundred or nearest ten to estimate
the number of boxes she still needs to sell? Explain.
Amy should round to the nearest ten so that her estimates are closer to the actual amounts.
If she rounds to the nearest hundred, she will get 200 for an estimate for the number of boxes sold. 200 is much higher than the actual amount, so she might think she only has to sell 100 more boxes when she really has to sell about 150 more.
