Question

Harriet counts 15 big boxes and 12 small boxes of notebooks. Each large box contains 189 notebooks, and each small box contains 79 notebooks. Estimate the total number of notebooks. Is your estimate an overestimate or an underestimate? Explain why it is better to have an overestimate than an underestimate.

Answer 1

Overestimate is better than underestimate because we easily count notebooks in each large and small box such that 15 big box* 189 books=2835 notebooks and 12 small box* 79=948 notebooks. Total= 3783 notebooks.
