x = -5
Hence, the number is -5.
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 ![f(b)=3.5b+24](https://tex.z-dn.net/?f=f%28b%29%3D3.5b%2B24)
We can see in the function 3.5 is multiplied to b, so when b increases , f(b) increases by 3.5.
![f(1)=3.5(1)+24=3.5+24=27.5](https://tex.z-dn.net/?f=f%281%29%3D3.5%281%29%2B24%3D3.5%2B24%3D27.5)
![f(2)=3.5(2)+24=7+24=31](https://tex.z-dn.net/?f=f%282%29%3D3.5%282%29%2B24%3D7%2B24%3D31)
![f(3)=3.5(3)+24=10.5+24=34.5](https://tex.z-dn.net/?f=f%283%29%3D3.5%283%29%2B24%3D10.5%2B24%3D34.5)
and ![f(2)-f(1)=f(3)-f(2)=3.5](https://tex.z-dn.net/?f=f%282%29-f%281%29%3Df%283%29-f%282%29%3D3.5)
Therefore, the value of 3.5 represents that for each birdhouse built, the total cost increases by $3.50.
