Answer:  A good estimation would be about 150.
Step-by-step explanation:
To estimate we can round instead of using exact numbers.
First day he saw about 30 birds and twice as many squirrels, meaning about 60 squirrels.  This is about 90 total when added together.
Second day he saw 20 birds and about 40 squirrels so about 60 when added together.
Add day one and day two totals for...
90+60=150

Answer:
<h2>
          y = 3.5x + 15</h2>
Step-by-step explanation:

y = 7/2 x
We need to add the 15 pairs from start.
y = 3.5x + 15
