Answer:
The cost of the building permit is $2,526
Explanation:
Let
n -----> the estimated cost of the building
f(n) ---> is the cost of the permit
we know that
![f(n) = 939 + 5.29(n-100,000)/1,000](https://img.qammunity.org/2020/formulas/mathematics/middle-school/qy7edp0apzr9ya0zn598rq86eht4l3w6bl.png)
we have
![n=\$400,000](https://img.qammunity.org/2020/formulas/mathematics/middle-school/yi768045f1jaod85quc7ghqcgshf77y1tj.png)
Substitute the value of n in the function above to obtain the cost of the permit
![f(n)=939 + 5.29(400,000-100,000)/1,000](https://img.qammunity.org/2020/formulas/mathematics/middle-school/f41jbu172mng6iy4z6g4s9s4o5iqeqp7v6.png)
![f(n)=939 + 5.29(300,000)/1,000](https://img.qammunity.org/2020/formulas/mathematics/middle-school/314plwn6na58xy83jkytocwi2dmm900y7i.png)
![f(n)=\$2,526](https://img.qammunity.org/2020/formulas/mathematics/middle-school/x2b2301dzhcohdhfdm6fcht3xumwdair64.png)
therefore
The cost of the building permit is $2,526
