Two students were asked to use estimation strategies to find
a reasonable solution to this question:
A market sells blueberries for $3 per pint. The first day, the
market sold a total of $35 worth of blueberries. The second
day, the market sold a total of $47 worth of blueberries. And
the third day, the market sold a total of $57 worth of
blueberries. Estimate how many pints the market sold over
the three days​
