Answer: For each birdhouse built, the total cost increases by $3.50.
Step-by-step explanation:
Given: The total cost for Sophia to build b birdhouses is represented by the function 
We can see in the function 3.5 is multiplied to b, so when b increases , f(b) increases by 3.5.



and 
Therefore, the value of 3.5 represents that for each birdhouse built, the total cost increases by $3.50.
Option B is the answer. The term for the geometric sequence that we have here is -3.
<h3>How to solve for the geometric sequence</h3>
We have u1, u2, u3 = a, ar, ar², ar³
From here we have to find the common ratio that is used to divide the sets of numbers
6,561 divided by −2,187 = -3
Hence when we go further each of the value when divided by -3 gives the next value.
Hence the value for the geometric sequence is -3.
