Answer:
71 birds.
Explanation:
First, let's take a look at the percentage. We are given 14 as the percentage. Now, we are going to move back the decimal point two spaces to the left.
14-> 1.4->.14
Now that we have 0.14, we are going to add a 1 to it, making it 1.14. This is because it is increasing, not decreasing. If it was decreasing, we would simply subtract 0.14 from 1. Next, multiply 1.14 by the original number of birds, so 150 total. The answer comes out to 171 total birds.
